GoTrue: Custom access token hook: Include current OAuth provider type

[bnjmnt4n]

I'd like to use the new Auth Hooks to customize some aspects of the login behavior based on the OAuth provider type used to sign in, via the custom access token hook. However, the access token hook doesn't provide any details about the current OAuth provider.

The docs claim there's a client_id field in the claims, so you might be able to use that:

"client_id": "oauth-client-id-if-oauth-flow"

What we ended up using was querying auth.identities for the most recently signed-in provider, like:

  IF v_auth_method = 'oauth' THEN
    SELECT i.provider INTO v_oauth_provider
    FROM auth.identities i
    WHERE i.user_id = v_user_id
      AND i.provider IN ('google', 'apple')
    ORDER BY i.last_sign_in_at DESC NULLS LAST
    LIMIT 1;
  END IF;

But this would definitely be nice to have in the hook payload directly.
