Hi, I'w been searching this extensively but not found an answer. When does FB tell the live broadcaster that someone has joinet to watch his/her feed? For example, when i browse my news feed or different groups i see people do their "lives" but i won't klick on them so its just the mute video for couple of seconds that i see while scrolling down. Still is it enough to tell the broadcaster that i have briefly joined the people that are watching him/her? Or is it when i unmute them or when i click on the live feed to zoom it?
