Honestly, our company uses ZOOM for these conferences. Have you had any problems with this application? If so, I suggest you contact
https://brightvisionevents.co.uk/conferences/live-conference-streaming/ to get it set up correctly. Or you can tell me how to configure it. Maybe you know better about it than I do. I'm trying to be as knowledgeable as possible so that the conferences don't break down in any way because significant people are attending them. Anyway, I would be glad to hear your suggestions. Our company is always open to coworking.
