How can I test/debug Google Sign In and Firebase?

I recently added in security rules to my firestore database, which means that Google Sign In on the Expo client actually needs to work in order for me to test my app. In this case, it doesn’t.

When I try to login to firebase authentication using the returned access token and idToken given to me by expo google sign in, I get a firebase auth error of IDP token not valid for this project.

I’m aware that the expo client has its own signatures, is there any way to add those to my firebase project so I can test Google sign in features on android? Or if anyone knows of another method to be able to test/debug standalone features without doing some sketchy stuff like printing to the screen, please let me know
