Face-to-Face Group Creation

Group Management

Group Roles

• Group Owner: The creator of the group with the highest management privileges
• Deputy Owner: Designated by the group owner to assist with group management
• Regular Member: Participates in group chat without management privileges

The group owner can set whether only the owner and deputy owner can manage the group, pin messages, and mention all members.

Member Management

• Group owner / deputy owner can add and remove members
• Can remove members with abnormal status (frozen or deleted) in one action
• Can add members to the pinned area and reorder them

Group Settings

Force Recall

Group owner / deputy owner can force-recall any message sent by any member at any time. Recalled messages become invisible to all group members.

Read Receipts

• View the read status of your sent group messages. Tap to view unread/read member lists and read times

• Groups with 200+ members do not show read receipts by default (adjustable by the operations platform)

Department Groups

A department group is a special group chat bound to a branch. When branch members change, the group membership updates automatically.

• A “Department” tag is displayed after the group name
• The group name defaults to the branch name but can be modified
• Choose whether to include members from sub-branches
• Department group administrators can remove members and add people outside the bound branch
• Removed members will no longer sync with branch changes
• Department group member limit is 3 to 500 (configured by the operations platform)
• When the bound branch is deleted, the department group becomes a regular group
