Can't access idToken using google play plugin for unity

I am using the google play games plugin and I set up everything correctly (I'm assuming). I've ran tests and I was able to log in properly. I then tried to get the user's email, id token and access token using the example from the plugin's page:

Debug.Log("Local user's email is " + ((PlayGamesLocalUser)Social.localUser).Email);
Debug.Log("AccessToken is " + ((PlayGamesLocalUser)Social.localUser).accessToken);
Debug.Log("IdToken is " + ((PlayGamesLocalUser)Social.localUser).idToken);

I am able to get the email and access token, but the id token doesn't work. I would have thought either they all work, or they all don't. I've tested putting debug.logs before and after getting the idToken alone, nothing happens after attempting to get it.

Any ideas what the problem might be?

 

Oh, never mind. I put in the wrong client id in during the setup. I put in the games client id instead the web app's one. Switched and it works.
