[ZPain8464]

Based on this Slack comment, write a guide that discusses best practices for configuring namespaces, users, service accounts, and any other related actions or features in the Console.

Possible areas to cover:

• Global namespaces
• Hierarchical policy enforcement and self-service capabilities
• RBAC in Enterprise Console: Cover roles and permissions (e.g. Admin, Manager, Viewer, etc.)
• Service Accounts: Creating and Authenticating service accounts
