How is the EU GDPR User Consent Code implemented according to the new updates of the IAB

Question

I'm in the process of testing EU GDPR user consent as per new IAB updates. I have created two functions to display the advertisement after the code is executed,

but I have no idea what is the appropriate function after the code is executed.

There are three options as follows:

UNKNOWN

NOT_REQUIRED

OBTAINED

This is my code it works normally I just need what can be done after that

package net.ads.ump;

public class MainActivity extends AppCompatActivity {

    private ConsentInformation consentInformation;
    private ConsentForm consentForm;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        List<String> testDeviceIds = Arrays.asList(Config.deviceIds);
        RequestConfiguration configuration =
                new RequestConfiguration.Builder().setTestDeviceIds(testDeviceIds).build();
        MobileAds.setRequestConfiguration(configuration);
        ConsentDebugSettings debugSettings = new ConsentDebugSettings.Builder(this)
                .setDebugGeography(ConsentDebugSettings
                        .DebugGeography.DEBUG_GEOGRAPHY_EEA)
                .addTestDeviceHashedId(Config.deviceIds).build();

        ConsentRequestParameters params = new ConsentRequestParameters
                .Builder().setConsentDebugSettings(debugSettings).build();

        consentInformation = UserMessagingPlatform.getConsentInformation(this);
        consentInformation.requestConsentInfoUpdate(
                this, params, () -> {
                    if (consentInformation.isConsentFormAvailable()) {
                        loadForm();
                    }
                },
                formError -> {
                });
    }


    public void loadForm() {
        try {
            UserMessagingPlatform.loadConsentForm(
                    this, setConsentForm -> {
                        MainActivity.this.consentForm = setConsentForm;
                        switch (consentInformation.getConsentStatus()) {
                            case ConsentInformation.ConsentStatus.REQUIRED:
                                if (consentForm != null) {
                                    consentForm.show(MainActivity.this,
                                            formError -> {
                                                loadForm();
                                            });
                                }
                                break;
                            case ConsentInformation.ConsentStatus.UNKNOWN:
                                // What is the appropriate function?
                                // loadAd_GDPR_IAB(); || loadAd();
                                break;
                            case ConsentInformation.ConsentStatus.NOT_REQUIRED:
                                // What is the appropriate function?
                                // loadAd_GDPR_IAB(); || loadAd();
                                break;
                            case ConsentInformation.ConsentStatus.OBTAINED:
                                // What is the appropriate function?
                                // loadAd_GDPR_IAB(); || loadAd();
                                break;

                        }
                    },
                    formError -> {
                    });


        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void loadAd() {
        MobileAds.initialize(this, initializationStatus -> {
        });
        AdView adView = findViewById(R.id.bannerId);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }

    private void loadAd_GDPR_IAB() {
        MobileAds.initialize(this, initializationStatus -> {
        });
        AdView adView = findViewById(R.id.bannerId);
        Bundle extras = new Bundle();
        extras.putString("npa", "1");
        AdRequest adRequest = new AdRequest.Builder().addNetworkExtrasBundle(AdMobAdapter.class, extras).build();
        adView.loadAd(adRequest);
    }
}

These are the two functions I created :

    private void loadAd() {
        MobileAds.initialize(this, initializationStatus -> {
        });
        AdView adView = findViewById(R.id.bannerId);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }

    private void loadAd_GDPR_IAB() {
        MobileAds.initialize(this, initializationStatus -> {
        });
        AdView adView = findViewById(R.id.bannerId);
        Bundle extras = new Bundle();
        extras.putString("npa", "1");
        AdRequest adRequest = new AdRequest.Builder().addNetworkExtrasBundle(AdMobAdapter.class, extras).build();
        adView.loadAd(adRequest);
    }

Also, is the code executed in the main activity of the application only, or should it be executed every class in which an advertisement is displayed?

This is the first time I have implemented an Admob code for EU Users Law Please help Thanks
