JitsiMeetJS.events.conference.TRACK_ADDED, onRemoteTrack" is not calling

Hello Everybody,
I have implemented Angular project using Jitsi Meet API (low level api).
I am not receiving any tracks in “JitsiMeetJS.events.conference.TRACK_ADDED, onRemoteTrack”.

when participant joined, inside onRemoteTrack i am not getting any track.

I connect to the room. I get User Joined info fine but I don’t get tracks. its not calling “onRemoteTrack” method.

does any one has solution on this issue ?

Please share a code sample of how you are using the APIs.
