Describe the bug
When implementing Google Sign-In on iOS, is it possible to indicate in the google account sign-in popup that only email address will be used?

To Reproduce
Steps to reproduce the behavior:

1. Implement google sign in using GoogleSignIn-iOS library
2. Build the app and press the google sign up button to proceed with the signup process.
3. In the google account integration popup, you will see that “name, email address, profile picture” are accessible in the user's account.

Expected behavior
I only need the user's email address. I want the popup to show the user that it only uses the email address.
As I understand it, name, email address, profile picture are the default public information in google account. However, I will only use the user's email address in my app via google sign-up, and I want the popup to show only the email address.
Is this possible?

Screenshots

Environment

• Device: any iPhone
• OS: any iOS
• Browser: N/A

Additional context
I've tested it without passing scope in the sign in request, and I've tested it with explicitly adding only userinfo.email as scope, but in both cases the sign-in popup shows that name, email address, profile picture are accessible. I want only the email address to be marked as accessible.

let additionalScopes = ["https://www.googleapis.com/auth/userinfo.email"] 
GIDSignIn.sharedInstance.configuration = config
GIDSignIn.sharedInstance
  .signIn(withPresenting: rootViewController, hint: nil, additionalScopes: additionalScopes) { 
      ...
   }

By default, GSI requests includes email and profiles scopes. You can see that here, and here.

So, this behavior is "works as intended." We can leave this issue open to see if folks would like an option only get the email scope.

I'll also share that this feature would be a fairly straightforward thing to add, and we could help with reviews, etc.

Thank you for your review. We need this feature in our service and are making the suggestions above.
I hope you will consider this proposal positively.

Hi @mdmathias , thanks for the context and guidance!

I've forked the repo and implemented a minimal change that adds only the email scope by default, while still supporting additional scopes if provided. You can find commit here

One thing I noticed during testing — even when the only granted scope is email, the Google Sign-In consent screen still says: “Google will share your name, email address, and profile picture…”

Let me know if there's a way to influence that message more precisely or if any changes are needed to generate the PR.

Looking forward to your feedback!
