Retrieve number of unread items

You can retrieve the count of a user's unread messages, unread mentioned messages, or invitations received in group channels and Supergroup channels. You can use this action to display the number of unread items in the UI so that users may check them. This is only available in group channels and Supergroup channels.

To get the count, use the getUnreadItemCount() method with UnreadItemKey.

The following table lists some of the properties in UnreadItemKey. To see the comprehensive list of all properties in UnreadItemKey, see the API reference.
