Get refreshToken react-native firebase and #react-native-google-signin/google-signin - firebase

Question

I need to get my accessToken and my refreshToken when I authenticate with fireabse. I have read a lot of the documentation and I can't understand how to get the refreshToken.
I get the accessToken from the GoogleSignIn.getTokens() method.
But I can't get the refreshToken from any method or function that these libraries provide me.
I need accessToken and refreshToken to send it to my backend. In other applications I am already receiving it, through other methods, but what would be the problem here? is the library wrong? I am not understanding the documentation? Why can't I really understand where to get it from or if the idToken updates itself or maybe the refreshToken is not sent anymore?
my code =>
import { GoogleSignin } from '#react-native-google-signin/google-signin';
import auth from '#react-native-firebase/auth';
GoogleSignin.configure({
webClientId:
'xxxxxxxxxxxxxxxxxxxxx',
});
const onGoogleButtonPress = async () => {
// Get the users ID token
const { idToken } = await GoogleSignin.signIn();
// Create a Google credential with the token
const googleCredential = auth.GoogleAuthProvider.credential(idToken);
// Sign-in the user with the credential
return auth().signInWithCredential(googleCredential);
};
export { onGoogleButtonPress };
