[Question]: How can I extract the generated nonce?

Question
In order to log in with Firebase Auth, I would like to have access to the generated nonce after OIDC login was successfull.
Perhaps something like this:

this.oidcSecurityService
      .checkAuth()
      .subscribe(async ({ accessToken, idToken, nonce }) => {
        const credential = provider.credential({
          accessToken,
          idToken,
          rawNonce: nonce,
        });
        await signInWithCredential(this.firebaseAuth, credential);
      });

As per the documentation of "@angular/fire/auth" OAuthProvider.credential:

The raw nonce is required when an ID token with a nonce field is provided. The SHA-256 hash of the raw nonce must match the nonce field in the ID token.

Looking at the source code, this doesn't look possible currently. I also don't see whether the generated nonce is actually SHA-256 hashed at all.

Help would be appreciated.
