VideoMediaReceived does not get called when AudioVideoPlaybackBot joins a meeting

I am using the latest version of AudioVideoPlaybackBot to join a meeting. In my case I do not see the VideoMediaReceived getting called. I looked into the code and CallHandler() constructor has this line

this.Call.GetLocalMediaSession().VideoSockets.FirstOrDefault().VideoMediaReceived += this.OnVideoMediaReceived;

However video on my case comes on socket #3, so shouldn't the code be

       foreach (var videoSocket in this.Call.GetLocalMediaSession().VideoSockets)
        {
            videoSocket.VideoMediaReceived += this.OnVideoMediaReceived;
        }

Please let me know if my understanding is correct or not.

Start with the CallHandler() constructor and the VideoSockets subscription shown in the issue. Check how AudioVideoPlaybackBot receives video when it joins and whether media can arrive on sockets beyond FirstOrDefault(). Done means confirming the socket-selection behavior and documenting or correcting the event subscription accordingly.
