Hide Video on/off button from the UI controls.
- Mostly people are doing audio-only meetings.
- As the video on/off button is just next to the Audio on/off button, many times people turn on the video accidentally
- And in current times when people are working from home all the time, it's a bit awkward to get the Video turned on accidentally
- Hide the video button under submenu
- Place audio and video button at a distance
- Add a secondary level of confirmation to turn on the video
