Example: You can set two Groups (Group 1 and Group 2) for two different geographical locations, A and B. Group 1 has access to the screens, media, and so on of Location A, and Group 2 has access to the same in Location B. Under each group, you can set the user roles (Manager/Operator/Editor). The Manager of Group 1 cannot see the screens, media, and so on of the Manager of Group 2, and vice versa.
Before creating a Sub User, you need to create at least one Group. Any sub-user must be linked to a Group when they are created.
