Cooking class on line thanks to Jitsi Meet with around 80 peolple : is it possible?

Hi ! I’m going to do a cooking class on line thanks to Jitsi Meet but I have far more participants than what I have been expected. We will be around 80 people : is it ok for Jitsi Meet ? And is it possible to freeze my window while I am cooking so that people can follow me ?
Thanks a lot for your help !
