[SOLVED] getCredentialAsync handle prompt dismiss

I'm making a android game with java, using CredentialManager to prompt the user to choose a Google account.

My code works but when the user taps outside the prompt, the prompt closes, but the OnCancelListener callback isn't invoked, nor is onResult or onError.

public void signIn_credentialManager() {
    String nonce = randomNonce();
    GetCredentialRequest request;
    googleIdOption = new GetGoogleIdOption.Builder()
        .setFilterByAuthorizedAccounts(false)
        .setServerClientId("...")
        .setAutoSelectEnabled(true)
        .setNonce(nonce)
        .build();
    request = new GetCredentialRequest.Builder()
        .addCredentialOption(googleIdOption)
        .build();
    CancellationSignal cancellationSignal = new CancellationSignal();
    cancellationSignal.setOnCancelListener(new CancellationSignal.OnCancelListener() {
        @Override
        public void onCancel() {
            // HERE NEVER TRIGGERED!
            log(LOG_TAG, "credentialManager.getCredentialAsync onCancel");
        }
    });
    cancellationSignal.throwIfCanceled();
    log(LOG_TAG, "credentialManager.getCredentialAsync");
    credentialManager.getCredentialAsync(
        context,
        request,
        cancellationSignal,
        executor,
        new CredentialManagerCallback<GetCredentialResponse, GetCredentialException>() {
            @Override
            public void onResult(GetCredentialResponse result) {
                log(LOG_TAG, "CredentialManagerCallback onResult");
                try {
                    ...
                }
                catch (Exception e) {
                    log(LOG_TAG, "CredentialManagerCallback Exception!");
                    e.printStackTrace();
                }
            }
            @Override
            public void onError(@NonNull GetCredentialException e) {
                log(LOG_TAG, "CredentialManagerCallback Error!");
                e.printStackTrace();
            }
        }
    );
}

Maybe CancellationSignal.onCancel is triggered only it I explicitely call .cancel on the request, if so how to handle the dismiss?

I also noticed that if the user click on "cancel" in that google prompt, the GetCredentialCancellationException will be thrown, so I would expect the same exception if the user touches outside that prompt, but instead it does not happen.

I'm using a Samsung Galaxy M53 5G with Android 14, Google Play system update May 1, 2024 and One UI version 6.0.

Edit:

I tried on my Samsung Galaxy Tab A (2018, 10.5) with Android 10 and One UI 2.1 and it throws GetCredentialCancellationException as expected.
