I've already tried to add the Selenium dependency but for now my pom.xml looks like this:

My code:

import java.net.MalformedURLException;
import java.net.URL;

import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;

import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;



public class CalculadoraTeste {

    public static void main(String[] args) throws MalformedURLException {
        DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
        desiredCapabilities.setCapability("platformName", "Android");
        desiredCapabilities.setCapability("deviceName", "emulator");
        desiredCapabilities.setCapability("automationName", "uiautomator2");
        desiredCapabilities.setCapability("appPackage", "com.google.android.calculator"); //CASO NECESSARIO UTIULIZAR O APP PACKAGER MANAGER E PROCURAR PELO APPPACKAGE OU APPACTIVITY
        desiredCapabilities.setCapability("appActivity", "com.android.calculator2.Calculator");
        desiredCapabilities.setCapability("noReset", "true");
        desiredCapabilities.setCapability("fullReset", "false");
        desiredCapabilities.setCapability("ensureWebviewsHavePages", true);
        desiredCapabilities.setCapability("nativeWebScreenshot", true);
        desiredCapabilities.setCapability("newCommandTimeout", 3600);
        desiredCapabilities.setCapability("connectHardwareKeyboard", true);
        
        AndroidDriver<MobileElement> driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), desiredCapabilities);
        
        MobileElement el3 = (MobileElement) driver.findElementByAccessibilityId("2");
        el3.click();
        MobileElement el4 = (MobileElement) driver.findElementByAccessibilityId("plus");
        el4.click();
        MobileElement el5 = (MobileElement) driver.findElementByAccessibilityId("2");
        el5.click();
        MobileElement el6 = (MobileElement) driver.findElementById("com.google.android.calculator:id/result_preview");
        el6.click();
    }
}
