cloud recording storage

Hello, I want to create a series of videos uploaded to the cloud for my class. I don't want them to distribute the videos, but when I upload the classes to google classroom, they only need the password to access the class... (or do they need to have a zoom account?). Well, what I want to know is if I can find out who enters the zoom classes, if the classes are shared, or if several people share the gmail to access from the classroom... especially this last option. thank you.
