title: Cloud composer: Unable to view Admin menu in airflow UI even after rbac=True & rbac_user_registration_code=Op
body: <p>I am setting up a composer environment,</p>
  <p>I have this IAM access: Composer Adminstator</p>
  <p>I have marked rbac=True &amp; rbac_user_registration_code=Op</p>
  <p>but I am unable to see admin menu in airflow UI &amp; also if I go to my profile in airflow UI it shows the user role as 'Viewer'.</p>
  <p>May I know  if I need to add Op/admin role anywhere else to be able to see it in menu.</p>
