[firebase-auth] How to obtain appleCredentialIdentityToken and rawNonce parameters not clear

[msn444]

The example code for Sign In With Apple functionality is as follows:

import { firebase } from '@nativescript/firebase-core';
import { OAuthProvider } from '@nativescript/firebase-auth';
const oauthCredential = new OAuthProvider('apple.com');
oauthCredential.credential(appleCredentialIdentityToken /* idToken */, rawNonce /* nonce */);

firebase().auth().signInWithCredential(oauthCredential);

Where is the appleCredentialIdentityToken and rawNonce obtained?

Looks like I may have missed the apple signin plugin in the example , please use https://github.com/EddyVerbruggen/nativescript-apple-sign-in to obtain the info mentioned

Thanks @triniwiz, that gets me a bit closer. A few more questions:

1. From signInWithApple() I get a SignInWithAppleAuthorization, which contains a credential object that contains an identityToken. Great, I pass that to oAuthProvider.credential(), but what about rawNonce? Do I actually need that and if so where do I get it?

2. Calling oAuthProvider.credential() doesn't seem useful on its own without passing the result to firebase().auth().signInWithCredential(). So I think the example code needs to be amended from :

const oauthCredential = new OAuthProvider('apple.com');
oauthCredential.credential(appleCredentialIdentityToken /* idToken */, rawNonce /* nonce */);
firebase().auth().signInWithCredential(oauthCredential);

to

const oAuthProvider = new OAuthProvider('apple.com');
const oAuthCredential = oAuthProvider.credential(appleCredentialIdentityToken /* idToken */, rawNonce /* nonce */);
firebase().auth().signInWithCredential(oAuthCredential);

3. Having done this, signInWithCredential throws an error, "INVALID_CREDENTIAL_OR_PROVIDER_ID". Do you have any idea what might cause this?

After some experimentation, it seems to work by calling oAuthProvider.credential() with an object that contains the identityToken as BOTH the idToken and accessToken keys, ie:
oAuthProvider.credential({idToken: signInWithAppleAuthorization.credential.identityToken, accessToken: signInWithAppleAuthorization.credential.identityToken});
