Turn off camera send no feed

If I am in a video call how do I turn my camera feed off?

I tried

localStream.getTracks().forEach(track => {
if (track.kind === ‘video’) {
track.enabled = shouldTurnOn

But this paused my video track, I want to send no video track at all when a user turns off the camera.

Far as i can tell currently, if you disable the video track then it sends blank frames instead.
Best way to deal with that would be to make the other client aware that the video tracks been switched off and then stop displaying the video.
