Question: How to force token refresh?

[vella-nicholas]

With reference to the Firebase custom claims documentation (https://firebase.google.com/docs/auth/admin/custom-claims#propagate_custom_claims_to_the_client), is it possible to achieve
An ID token is force refreshed by calling currentUser.getIdToken(true) using angular fire?

Thanks in advance!

currentUser is returned as a promise in AngularFire. So need to do:
(await this.fireAuth.currentUser).getIdToken(true)

Another option is you don't have to use AngularFire for this but just the firebase js sdk and do:
firebase.auth().currentUser.getIdToken(true);

...so long as you are importing...
import firebase from 'firebase/app';
import 'firebase/auth'

I confirm this works. For anyone using Observables, this is my solution:

public getToken$(): Observable<firebase.auth.IdTokenResult> {
    return from(this.angularFireAuth.currentUser).pipe(switchMap(user => {
      return from(user.getIdTokenResult(true)).pipe(map(token => {
        return token;
      }));
    }));
  }

  }

Thanks for the tip 👍

With one line format:

public token$ = from(this._angularFireAuth.currentUser.then(user => user?.getIdTokenResult(true)))
