Group Therapy screen appearance

I was using free zoom for my group therapy - typically 4 clients. So, I figured if I’m gonna pay for an upgrade it should be for doxy since I’m on it all day for individual session.

Last night I had my first group on doxy and the user experience was terrible. What am I doing wrong? Everyone’s little windows were stacked on top of each other on the right side of the screen. How can I make the layout of attendees spread out and look like a zoom screen?
