Security Permission in appian

We have four user roles: Admin, Manager, Supervisor, and Agent.

• The Agent performs certain actions that are accessible to all three higher roles (Supervisor, Manager, and Admin).
• The Supervisor performs some actions that should be accessible only to the Manager and Admin.
• The Manager performs specific actions that only the Admin should have access to.
• The Admin can perform exclusive actions that no other role can access.
