I have question in function SignInService

[GundamD]

I develop function sign in google and huawei, In section google, I config require id token in cloud and when use in old function config with

 GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken([IdToken])
            .build()

But I can't set id token to library and when I look in library (GmsSignInService) I find that library doesn't have a set token part . Or is there any other way to set id token for google login?
