-  * If desired, the developer can provide a unique thread ID to start the group call or add participants. In this case, the ACS Calling SDK will use the given thread ID to create the group call. A chat thread is created for the Teams users and this thread is associated to the group call for users in Teams app. This allows them to chat during the call.
