What’s the difference between Group admin and Group owner?

Group owner is the person who created the group and manages all aspects of the group. Group owner can appoint admins who can moderate and monitor the group activities. Group owner is the only person who can deactivate and delete the Group.

Depending on the Group type and level, a Group may have 3-12 admins. Group admins can moderate  group chat and remove members in case of violations.
