Is it necessary to have several licenses? Hi,This is my first time using Zoom. If you could give me some advice on how to proceed with the following requirements, I would greatly appreciate it:An online tutor will teach a group of up to 12 students using Zoom.Lessons last about an hour each.The assignment takes 12 hours, one hour a day, over three weeks.Five tutors will teach different groups (details above)Zoom Basic is used by both tutors and students.There will be a need for Screen Sharing, Breakout Rooms, Team Chat, and Whiteboarding for tutors.I will upgrade to Zoom PRO.Questions:1. For each tutor, do I need to purchase a PRO license?2. Also, does Zoom PRO need to be purchased by each participant (student)?3.Even in a "Breakout Room", tutors should speak with students. Could that be done?4. Can I cancel a tutor's license after they complete their assignment after three weeks, and ask for it
