The add-in is displayed in the group chat client in a panel beneath the chat area. The chat room interacts with the add-in, sending it notification of inbound and outbound messages. The add-in also has access to metadata about the chat room and the messages which are posted to it.
An add-in must be registered with the system before it can be used on a chat room. The list of registered add-in may be obtained from BeginGetAllAddIns(AsyncCallback, Object) . See BeginRegisterAddIn(GroupChatAddInSettings, AsyncCallback, Object) for more information about registering add-ins.
