At times participants unmute themselves and also show themselves on the video when they are actively speaking and participating. After that it is possible that they may not even speak for a long time but they forget to mute themselves and we hear some weird audio from their backgrounds and that can cause interuptions or some fun situations and then someone has to ask them to mute themselves.If there is a setting to auto-mute participants if they have not spoken for 1-2 minutes (Configurable?) that will prevent such situations and a message or some other graphics can be shown on their meeting that you have been auto-muted and they can unmute themselves again if needed.Can be done for video too.
