Requirement: To deactivate a group, you must be the admin of this group.
First, navigate to “My Groups” using the drop-down menu at the top right of the header.
Then select the group you want to deactivate and then click “Settings”. If you scroll down you will find the “Disable Group” option.
Note : It is not possible to completely delete a group in Sdui . Groups that are no longer needed can only be deactivated.
