title: Google Cloud list all users in a project when assigned by group permissions?
body: <p>Instead of adding users directly to a project we are adding them to groups which are then assigned permissions.</p>
  
  <p>When using commands like: <code>gcloud projects get-iam-policy MY_PROJECT</code> it returns the name of the group and service accounts within the project.</p>
  
  <p>What command can I run to return users within each group?</p>
  
  <p>Thank you,
  Ari </p>
