Is a paid plan need to take a long course from another company?

I will be taking a 2-day training course that an outside company is holding over Zoom (not a course that is offered by Zoom). Each day will consist of a live 7-hour training "meeting". Since the meetings will be more than 40 minutes, do I need to sign up for a paid Zoom plan in order to take the course? I don't want to be kicked off after 40 minutes.
