Shield - 2FA for only some users

Thank you, Thats great help.
I will star that location to check for further questions and checking before asking.
Already helped with my SyncGroups not working.

I have just about got extending the Email2FA working.
Simply bypassing createIdentity() method doesn't seem to work,
I have to bypass the return view(setting('Auth.views')['action_email_2fa'], ['user' => $user]); as well.

However the Show() function requires a string to be returned, but if I want to redirect()->to() it fails as not a string.
if I removed the : String requirement it throws an error because I have to follow the parent (Email2FA) rules.

Can you help direct me a bit here?
