I don't think this still exists in the google cloud console

Google+ API is still in the Google Cloud Console:

From what I understood you need to active the API as a whole but perhaps I'm mistaken here.

google+ is deprecated and currents (enterprise google+) is being sunset in favor of google chat spaces (not the other spaces...) so I guess it's dead. The docs links leads to a 404, I think it's going to be removed as soon as currents is dead.
