After setting up the environments required by the organization, admins can modify existing roles (except the Project Admin role, which cannot be modified) by assigning these environments to the relevant roles:
A Project Admin can assign global and project environments to project-specific roles.
A Platform Admin is required for assigning global environments to global roles.
The roles, which are assigned to groups and users, determine which actions can be performed on the resources contained in the environment.
Custom global environments are added to the Project Admin role automatically.
