Ability to Hide Team Members from Other Teams

Our Company run's multiple business out of Front. We need the option to either separate or hide the team mates who are not part of the other groups. Where Only the users who have access to the Shared workspaces, are able to see other members of that workspace.

Example:
Team 1
User A, User B, User C

Team 2
User D, User E, User F

User A has access to both Team 1 & 2 and should be able to view all teammates of both teams.
User B has access Only to team 1 and should not be able to see Users D, E & F
User D has access Only to team 2, and should not be able to see Users A, B & C.
