What are the roles available in an app?

When you invite a member to an org, and subsequently grant access to an app, you can assign them the following roles

• Admin: This role has complete access to the app and can assign roles to other members. However, Members with limited access cannot invite or list the other members in the app.
• Developer: This role cannot see any private information of the end-users or other members of the app. This role can see the infrastructure details.
• Customer Support: This role can see private information but cannot see any infrastructure details.
