Viewer not receiving broadcast event "updated" or "track" events when publisher switches off video/audio

[jaya-kumar-softobiz]

Hi guys, the doc below says that "updated" event will fire when a video/audio track is added or removed to a feed
https://docs.dolby.io/streaming-apis/docs/viewer-events
But we are not receiving those events in viewer.on("broadcastEvent", handleBroadcastEvent) even though the viewer subscribed to it using view.connect()
The viewer is receiving all other events like active/inactive/layers/viewercount except this "updated" event
We need this event because we want the viewer to know that a publisher has switched off their audio/video (i.e mic/camera)

I was expecting a source.publish.webRTCPeer?.replaceTrack(audioTrack) will trigger that but got nothing.
Then I tried to remove the track completely but still nothing source.publish.getRTCPeerConnection().removeTrack(rtcRTPSenderAudioTrack)

Even checked the track events viewer.on("track", handleTrack).
source.publish.webRTCPeer?.replaceTrack(audioTrack) or source.publish.getRTCPeerConnection().removeTrack(rtcRTPSenderAudioTrack) is not triggering a "track" event either

Track events are being received only during "active" broadcast event. When a source starts with both camera and mic on, Viewer gets an "active" broadcast event followed by two "track" events (audio and video). But now if the source stops mic/camera, the changes are reflected on the viewer UI immediately but not receiving any events

We are using latest version of millicast sdk. How are these "updated" broadcast events triggered exactly when the Publisher changes the video/audio track? Please help
