Adding users to groups is the easiest way to grant users access to different workspaces. Indeed, rather than multiplying the number of users access to a workspace, you can add users to a group and grant group access to a workspace. 

Add users to a group

To add a user or multiple users to a group:

1. Go to the Admin tab > Groups. 
2. Open a user group.
3. Once in a specific group, go to the Members tab.
   A list of this group's members will be displayed.
4. Click + Add members.
   
5. Select one or more users and click Confirm.
   The selected users will be displayed in the group member list.
