thisuser is undefined when you fetch data from the appcomponent in angular -oidc-client

I created an Initializer like this

import { AuthService } from "./auth-service";
export function AuthInitializer(auth: AuthService) { return () => auth.isAuthenticated() };

and registered like this in core.module

providers: [

{
  provide: APP_INITIALIZER,
  useFactory: AuthInitializer,
  deps: [AuthService],
  multi: true
}]

this is working perefectly.
