Do we need a real app to provide "Sign in with Apple" on a website?

The question is do we need to provide a real iOS/Mac app in order to provide this functionality.

Would it be enough just to create an App ID (call the app "[Company] Account" for instance) and use it to implement the Sign in with Apple functionality on our website without going through the app review?
Any chance anyone from Apple could reply?
