Receive an RCS sender launch update event

When a launch request is submitted for a given RCS sender, the launch status is updated individually for each provider within the selected country. This webhook delivers real-time updates whenever the launch status changes for any provider in any country. To receive these events, you must subscribe to the RCS channel and specify the SENDER_LAUNCH_UPDATE event. For more details on managing subscriptions, please refer to the Subscriptions Management documentation.
