Hi! I'm trying to enable my camera and microphone by using

await room.localParticipant?.enableCameraAndMicrophone();

but my pc has no plugged in camera. for this reason it gives me the error. but the problem is, If it unable get the camera, then

RoomEvent.LocalTrackPublished

and

RoomEvent.TrackSubscribed

those events aren't work. In this two events I'm rendering the participant's streaming video.
