How to retrieve Googleplus idToken



I’m using googleplus native login in my app with ionic 2, as outlined in the ionic documentation.

The app is working fine but I would like to authenticate on the server (and retrieve the google id) and for this I need the idToken from google, but I can’t see it anywhere in the result from the googleAuth.login function.

The cordova.plugin-googleplus documentation mentions that it should be provided.

Many thanks for your help!
