How to implement video communication between a tutor and a student on the site?
I'm going to make a site for tutors, I found a similar one, communication between a student and a teacher is very conveniently implemented there, there is even a board, here's an example https://www.tutoronline.ru/how-it-works/demo
How to implement something like that, just a video, maybe there are some services that have their own API?
