//
// The ability to add or remove a participant to/from the conversation will change over the
// life-cycle of the conversation. This will informed through the ActionAvailabilityChanged
// events.
//
// Whenever a participant joins or exits the conversation, events ParticipantAdded or
// ParticipantRemoved will be raised. Those will occur either by an action taken at this
// endpoint or any other participant in the conversation. For example, a ParticipantAdded
// may be fired because the other side of the conversation added a new contact to the
// conversation.
