To remove a member of your workspace, navigate to the Grain Menu Bar in the top right corner --> 'Workspace Settings'.
Scroll down to the user you want to remove and click the three vertical dots next to the user's name --> Remove them from their Grain plan --> then 'Suspend Member'.
When a User is Suspended:
The user can no longer log in
The user’s shared recordings are still available
The user’s private recordings will be restored if unsuspended
