React Native Google Sign In User Birthday Access Problem - react-native

Question

I am trying to get user birthday when user is registered with Google Sign In and want to display his/her info in the profile page.
Google Sign In was implemented via firebase.
And then, I went to google developer console and made
Added People Apis and then go to OAuth consent screen
Select External
Added App domain, Authorized domains, Developer contact information
Added birthday scope
Added test users
Save and Back to Dashboard
Birthday info is set as public
The problem is still my test users cannot login to Google. It says "Access Denied. your app did not complete the google verification process. The app is currently being tested. Only approved test users can access the app."
I can only login with my developer account.
And when I logged in, in the console, I can see the birthday scope is added in scopes array. However the birthday info is still not in my user object.
I use "#react-native-google-signin/google-signin": "^6.0.1" package.
Can someone help me please ?
Do I need to verify the domain/owner to be able to see birthday info ?
Or the package does not support this info ?
Why my test users cannot login even though I added them ?
My code is below
export const auth = {
initGoogleSignIn: function () {
GoogleSignin.configure({
scopes: [
'https://www.googleapis.com/auth/user.birthday.read',
'https://www.googleapis.com/auth/user.gender.read',
'https://www.googleapis.com/auth/plus.login',
],
// scopes: ['https://www.googleapis.com/auth/plus.login'],
webClientId: Config.GOOGLE_WEB_CLIENT_ID,
offlineAccess: false,
});
},
};
import auth from '#react-native-firebase/auth';
export const googleLogin = () => {
return async dispatch => {
try {
await GoogleSignin.hasPlayServices({showPlayServicesUpdateDialog: true});
const isSignedIn = await GoogleSignin.isSignedIn();
if (isSignedIn && Platform.OS === 'android') {
await GoogleSignin.revokeAccess();
}
const {idToken} = await GoogleSignin.signIn();
const token = await GoogleSignin.getTokens();
dispatch(handleSocialSignup(COMMON.GOOGLE, token?.accessToken));
// Create a Google credential with the token
const googleCredential = auth.GoogleAuthProvider.credential(idToken);
// Sign-in the user with the credential
const userSignIn = auth().signInWithCredential(googleCredential);
Alert.alert(JSON.stringify(userSignIn));
userSignIn.then(user => Alert.alert(user)).catch(err => console.log(err));
} catch (error) {
if (error.code === statusCodes.SIGN_IN_CANCELLED) {
console.log('Cancelled by user');
} else if (error.code === statusCodes.IN_PROGRESS) {
// operation (e.g. sign in) is in progress already
} else if (error.code === statusCodes.PLAY_SERVICES_NOT_AVAILABLE) {
// play services not available or outdated
} else {
Sentry.captureException(error);
Sentry.captureMessage(strings.common.undefinedError);
console.log('some other error happened', error);
dispatch(showSnackbar(strings.common.undefinedError));
}
return false;
}
const [googleUserName, setGoogleUserName] = useState('');
const getGoogleUserName = async () => {
const currentUser = await GoogleSignin.getCurrentUser();
setGoogleUserName(currentUser);
console.log('currentUser', currentUser);
};
useEffect(() => {
getGoogleUserName();
}, []);
console.log('googleUserName', googleUserName);
