Is it necessary to attach a configuration file

Trying to get tokenId when registering via Google LogIn button.

Now it works like this for me, I just registered in the Google console of the Web and Android and when prompted in the method

 @NonNull private GoogleSignInOptions getGoogleSignInOptions() { return new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestIdToken(context.getResources().getString(R.string.server_id_test)) .build(); } 

I use WebId and everything works.

But then I created another account in the google console and did the same there, and when I now use WebId from the second account, I get a response

Status {statusCode = unknown status code: 12501, resolution = null}

I read what I can do and didn’t find anything sensible, I’m doing everything as it should be, the only thing different is that some developers download the Google Configuration file and put it into the project.

But why, then, in my first case, I did not download any file and it works, but in the second case, no ...

Do you need to download this file and if so where to put it?

From where do I get google-services.json or not here?
