idToken undefined in result.authentication (authSession with Google)

Summary

When getting a response back from promptAsync using AuthSession with Google, I get an authentication value with an undefined id_token. I know I can get the id_token by itself but I’m looking for both an access token and id_token in the same response because I can’t think of an elegant workaround to get both separately using this library (each would have to prompt the user with a popup, and worse you would have to trigger popups by asking the user to click two buttons or disable pop up blocker)

Reproducible demo or steps to reproduce from a blank project

Just using the same code as in the docs – but not doing it on snack (since you can’t even enter your credentials there with google sign in). Other people have also seen this bug, see these links: https://stackoverflow.com/questions/66966772/expo-auth-session-providers-google-google-useauthrequest and https://forums.expo.io/t/expo-auth-session-google-useauthrequest-returns-googles-idtoken-value-as-undefined/49510

Same here: There seems to be a bug in the expo-auth-session/providers/google v 3.2.3 package that returns idToken as undefined when calling Google.useAuthRequest. I’m testing on Expo Go, everything configured correctly as documentation says, web proxy credentials, everything. The only solution that worked for me to get idToken is this code provided by howard:

   const [request, response, promptAsync] = Google.useAuthRequest({
      responseType: "id_token",
      androidClientId: process.env.GOOGLE_CLIENT_ID_ANDROID,
      expoClientId: process.env.GOOGLE_CLIENT_WEB_EXPO,
      scopes: ["email"]
   });

This code is a workaround to get idToken (in the “params” key) and no other data.

The old package expo-google-app-auth seems to be returning idToken correctly along with other data.

Edit: I’ve found Google.useIdTokenAuthRequest that can be used instead of Google.useAuthRequest but seems to do the same thing than the code above. Maybe by design in the package it’s not possible to get idToken and other information at the same time. Also this Google.useIdTokenAuthRequest hook is undocumented except when you click on the firebase tab in the code example of this page

Same issue here. Using Google.useAuthRequest and the idToken on the response object is undefind.
