Learn how to assign moderators and admins in a group.

Change Scope of a Group Member

In order to change the scope of a group member, you can use the changeGroupMemberScope().

var GUID = "GUID";
var UID = "UID";
var scope = CometChat.GROUP_MEMBER_SCOPE.ADMIN;

CometChat.updateGroupMemberScope(GUID, UID, scope).then(
  response => {
    console.log("Group member scopped changed", response);
  },
  error => {
    console.log("Group member scopped changed failed", error);
  }
);

This method takes the below parameters:

Parameter

Description

UID

The UID of the member whose scope you would like to change

GUID

The GUID of the group for which the member's scope needs to be changed

scope

The updated scope of the member. This can be either of the 3 values:
1.CometChatConstants.SCOPE_ADMIN (admin)
2.CometChatConstants.SCOPE_MODERATOR (moderator)
3.CometChatConstants.SCOPE_PARTICIPANT (participant)

The default scope of any member is participant. Only the Admin of the group can change the scope of any participant in the group.

Real-Time Group Member Scope Changed Events

In other words, as a member of a group, how do I know when someone's scope is changed when my app is running?

In order to receive real-time events for the change member scope event, you will need to override the onGroupMemberScopeChanged() method of the GroupListener class

var listenerID = "UNIQUE_LISTENER_ID";

CometChat.addGroupListener(
  listenerID,
  new CometChat.GroupListener({
    onGroupMemberScopeChanged: (
      message,
      changedUser,
      newScope,
      oldScope,
      changedGroup
    ) => {
      console.log("User joined", {
        message,
        changedUser,
        newScope,
        oldScope,
        changedGroup
      });
      // Handle Event : user joined group
    }
  })
);

Missed Group Member Scope Changed Events

In other words, as a member of a group, how do I know when someone's scope is changed when my app is not running?

When you retrieve the list of previous messages if a member's scope has been changed for any group that the logged-in user is a member of, the list of messages will contain an Action message. An Action message is a sub-class of BaseMessage class.

For the group member scope changed event, in the Action object received, the following fields can help you get the relevant information-

  1. action - scopeChanged
  2. actionOn - User object containing the details of the user whos scope has been changed
  3. actionBy - User object containing the details of the user who changed the scope of the member
  4. actionFor - Group object containing the details of the group in which the member scope was changed
  5. oldScope - The original scope of the member
  6. newScope - The updated scope of the member
