React Native - mute/unmute process flow


I am totally new to react native & video conferencing application. Somewhat I went though the code & little bit understood the join conference process. But I have been trying to understand the video mute & unmute process past one weeks. I am not able to get it. I wanted to know when I mute/unmute the video which event emitter & listeners are called to update the process to local & remote users.

Can someone explain me this process flow completely?

It would be very much helpful. Because I am scratching my head past one weeks
