Property 'accessToken' does not exist on type 'AuthCredential'

[ty.sh...@gmail.com]

Following this guide https://firebase.google.com/docs/auth/web/google-signin

I've use these instructions before in Angular 5, now that I'm using Angular 7 these instructions don't seem to work.

I get Property 'accessToken' does not exist on type 'AuthCredential'

Is this something to do with Angular 7 or is there some new firebase documentation?
