react native kiosk mode listen to unpinning from device buttons

Question

I want to implement kiosk mode on react native (android). I have implemented the functionality to pin/unpin application and check if lock task mode is active using activityManager.getLockTaskModeState, startLockTask & stopLockTask.

The problem is i cannot track when user unpin the app by pressing recencts/back buttons.

i tried to add event listener with following code without success

    public void registerLifecycleEventObserver() {

        UiThreadUtil.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                AppCompatActivity activity = (AppCompatActivity) reactContext.getCurrentActivity();

                activity.getLifecycle().addObserver(KioskModeModule.this);
            }
        });
    }
    @Override
    public void onStateChanged(@NonNull LifecycleOwner source, @NonNull Lifecycle.Event event) {

            boolean isKioskEnabled = isLockTaskModeActive();
            if (this.isKioskEnabled != isKioskEnabled) {
                this.isKioskEnabled = isKioskEnabled;
                WritableMap args = Arguments.createMap();
                args.putBoolean("isKioskEnabled", isKioskEnabled);
                sendEvent("onKioskStateChange", args);
            }

    }

Any idea on how i can listen to kiosk mode state change?
