Firebase 3 - javascript - get facebook accessToken after login

Question

In Firebase 2 I was able to get facebook accessToken from anywhere after login by this way, just using the firebase reference, eg:

firebase.getAuth().facebook.accessToken

Now, how can I get that in version 3 (web)?

Note, I need it outside of the Promise signInWithPopup

Thanks

I just found this on documentation... Why? :(

Since Firebase Authentication no longer persists the access token, your application will have to do so itself, if needed.
