Permission Inheritance will only be visible for Enterprise-level subscriptions, for Administrators managing multiple spaces or floors within one building for a unified team.
Assigning Permission Inheritance allows an Admin to associate any SSO or Whitelist/Blacklist settings from another configured Space with the current Space, without the need to re-create them in the current Space. This connection is dynamic, so that if the settings are updated on the linked Space, they will correspond for the current Space as well.
