Limiting a member to named projects
A member can be restricted to named projects when they are invited or later. They see those projects, images used on those projects or uploaded by them, and the people working on those projects. The rest of the workspace is not shown to them.
To do it when inviting, choose the projects under Access before you press Invite. To do it later, open the person on Settings, then Members, and change what they can see. The projects they are on can be changed at any time, and an owner or admin can give them the whole workspace again.
Admins cannot be restricted. If you need somebody to see one job only, invite them as a member.
Restricted access is included on every plan.
