Due to security settings, you are only allowed to add users to groups that you belong to yourself. If you have back office "staff" permissions yourself, check how to add this permission for new and existing members of the platform.
Add new members of the platform
To add a new member, go to the side menu and click on 'Users', and on the right on '+ Add member'.
Fill in the details. Select the box 'Staff status' and select 'Staff' in the dropdown. Don't forget to save! The automatic welcome email is sent to the new member.
Add permissions to existing members of the platform
Simply look up the specific user account. You can find all members via the side menu in the back office > click on ' Users'.
Go to the tab 'Permissions' > select the box 'Staffstatus' and select 'Staff' in the dropdown. Don't forget to save!
