Add A Sample To Documentation for Refresh Tokens in Mobile Angular and/or Cordova

Is your feature request related to a problem? Please describe. I am following this article Securing a Cordova App

Describe the solution you'd like The library has changed and would like to see a best-practice or how-to documentation for mobile. seems the checkAuth needs to behave differently and am not entirely sure how to update/change a guard to behave if we have a custom checkAuth.

Describe alternatives you've considered No other libraries. Custom guards but need access to methods that were previously exposed in v11 (via AuthStateService)

Hey, basically the article describes the way a cordova app would handle the auth request. You need to a custom URL scheme to redirect into your app after the redirect from the sts. In addition to that, you need to pass the url to the checkAuth() method. That is the key points for cordova.

I have everything working now, just unsure if i should be using a custom guard or still use the default provided guards.

I have added a working example here https://github.com/FabianGosebrink/cordova-angular-oauth2-oidc. Also added to the docs Mobile Sample using Cordova
