Hi @mohammadz, thanks for your patience here. There is no equivalent currently as the auth0-angular package is designed to completely manage this for you. It uses the auth0-spa-js SDK under the hood (which does have checkSession functionality) when the SDK initializes, but this in turn calls getTokenSilently under the hood to manage the refresh of ID/access tokens and rehydrate the user state.
In short, you shouldn’t need to call this yourself when using auth0-angular.
Hope this helps!
