How To Perform a Side-by-Side Zoom Webinar

Greetings

I hope to make this question clear,

I want to make a Zoom session with side-by-side as per the following pic

What is my procedure for doing this?

My side-by-side is "checked" but not helpful

I have Basic-Zoom. Do I need be on the "Pro" level to execute this? 

Windows 11, 

thanks, Ken,
