Great news! We just started working on this for the AUDIO portion. We are still trying to determine feasibility for the video portion of your request.

Love this feature on the phone. Definitely wish that it was available on desktop. One thing that would also be helpful is if in settings a user can toggle push to talk so they dont have to have their finger on the record button the whole time. Our team uses a lot of voice recordings on the road, so this would be good for us to have.
