Account for Login/Authentication

If I'm not mistaken the Readme shows examples of how to use this library but doesn't show how to handle the situation where a user is logged out tries to open a deeplink. Where should that logic live that will check if a user is logged in or not? Then after a user signs in , will the deeplink be deferred, will the user be taken to the location of the original deeplink?

Some sample code of how to accomplish this task would go a long way.

Start with the README's existing deep-link examples and review how the library handles incoming links. Determine what guidance is needed for logged-out users, sign-in completion, and deferred navigation, then document a sample flow and its expected behavior in the README.
