I still cannot login. Do we need to be whitelisted

PLEASE help. I have been trying for weeks to get into sketchup for education. Our administrator has deployed it. It is on our google navigation menu. I try to login with my google login and I get the message

Please ensure that:

  1. You are using a G Suite for Education or Microsoft Education account.
  2. Your G Suite administrator has installed SketchUp for Schools on your domain and granted permissions.
