Signout federated user permission dialog

[milannikolic1]

Describe the bug

When calling the signOut method in Amplify Auth, a system permission dialog appears. When federated user is signedin

Expected behavior:
No permission dialog should appear during sign-out.

Actual behavior:
A permission dialog is unexpectedly triggered when signing out.

Steps to reproduce:

User is signed in.

Call Amplify.Auth.signOut().

Observe that a permission dialog appears.

This issue prevents a smooth sign-out experience and may confuse users since no new permissions should be requested at this stage.

Steps To Reproduce

Steps to reproduce the behavior:
1. let signInResult = try await Amplify.Auth.signInWithWebUI(for: .google)
2. after succesfully sign in 
3. await Amplify.Auth.SignOut()
4. permission dialog is shown (not needed)

Expected behavior

The expected behavior is that signing out should not trigger any permission dialogs

@milannikolic1 Part of a successful web sign out is launching the browser and clearing the Cognito cache in the browser. If you set preferPrivateSession, customers will not see this: https://docs.amplify.aws/swift/build-a-backend/auth/sign-in-with-web-ui/#prefer-private-session-during-signin

@tylerjroach Yes i tried that but when i set preferPrivateSession, when user signin must type in email and password doesnt have to choose account list, But for me is bad user experience to get this dialog with type "signIn" a user try to signout, little messy
