Which roles can be assigned? Why are there only 2 roles available?

Currently we have 2 roles that can be assigned - User and Super Admin.
  1. User refers to team’s members who are added to the plan and can book workspaces. They do not have access to the dashboard.
  2. Super Admin are the team’s admins who have complete access to all settings and functions of the dashboard
