Not all students are the same, there are some that being at home, they find it difficult to concentrate for class since they are in the place where they usually relax.

I once had a student who when I went to his house to teach him he could not concentrate, he wanted to go to the bathroom every so often, look for something in his room, drink water or show me something interesting about his home, it was difficult for him to understand that it was a moment for study.

I told her mother that it was best to teach him in the classroom even though the mother wanted the class to be at her home. In the classroom he was not distracted as at home. He was the only one with that concentration problem, with my other students that I taught at home, they concentrated easily.

When the pandemic started, we knew that this child could not hold virtual classes, he would lie in bed to watch the class. Something that I do not recommend since the brain will tell him that it is time to sleep!
Virtual classes are not for everyone, virtual classes are for independent and self-taught students, students who find it easy to concentrate and do not need a parent to watch them.

When I started giving online lessons, I was very sleepy, can you imagine falling asleep being the teacher? ha ha ha
I learned that I had to take a good bath, dress like I was going to go out no matters the students wouldn't see me because I wasn't going to share the screen. Doing a whole ritual before class like putting on makeup, told my brain that it was time to work and not to relax.

The other thing is that ... In online classes with a single student it has an advantage but with classes with very large groups, it is difficult to keep them all active, if the group is small one can invent a dynamic where everyone participates continuously, but in a large group becomes difficult. When the student has a very passive role, he gets bored.

There are pages on the internet that serve as support. For example, everyone solves quizzes at the same time or plays, but not all classes can be this way, at some point the student will have to assume a passive role if he is in a large group.
