having to start about thirty meetings, I wanted to know if there is a tool or a CLI to quickly start multiple meetings. I just have to start, I'm not interested in participating

Can I view a particular meeting participant in full screen or in a larger pane or zoom in? even if the participant is not talking but only has the webcam turned on?

I am the organizer of the meeting. I don't see a participant's video, instead other participants see. How is it possible?
