Setting `signInOptions.disableSignUp.status = true` for `GoogleAuthProvider` still allows new users to register.

[REQUIRED] Describe your environment

• Operating System version: macOS 11.4
• Browser version: Chrome 91
• Firebase UI version: 4.8.0
• Firebase SDK version: 8.6.8

[REQUIRED] Describe the problem

Setting signInOptions.disableSignUp.status = true for GoogleAuthProvider does not work as expected and still allows new users to register.

Steps to reproduce:

1. Initialize using the following signInOptions:

signInOptions: [
    {
      provider: firebase.auth.GoogleAuthProvider.PROVIDER_ID,
      scopes: ["https://www.googleapis.com/auth/userinfo.email"],
      disableSignUp: {
        status: true,
      },
    }
]

1. Try to sign up via Google with a new account

Relevant Code:

Expected: New users can not sign up with this provider set to disabled

Actual: New users can sign up and create new account with this provider.

Note: the option does work as expected with email provider.

@davidbielik Thanks for the advice, we’ll make it more clear in the doc.

Thanks @xil222 looks like this feature is beyond a simple Firebase integration (it’s a separate API I need to enable). If that’s the case, it might be worth clarifying the conditions to use it in the docs.
