TrackPublished = "trackPublished"

When a new track is published to room after the local participant has joined. It will not fire for tracks that are already published.

A track published doesn't mean the participant has subscribed to it. It's simply reflecting the state of the room.

args: (RemoteTrackPublication)

TrackStreamStateChanged = "trackStreamStateChanged"

StreamState indicates if a subscribed track has been paused by the SFU (typically this happens because of subscriber's bandwidth constraints)

TrackUnpublished = "trackUnpublished"

A RemoteParticipant has unpublished a track
