Zoom display

My daughter is in a zoom class. Before I set up a free account, it would automatically default to the teacher and if she would share her screen it would transition to that and then back to her when she wasn’t sharing. Simultaneously, all the participants were in smaller boxes at the bottom. However, since I created the free account, I can’t, for the life of me, figure out how to get that back. I’ve tried doing gallery with speaker view but that doesn’t work. And the floating option.
