Hiding a Video

Hello everyone,

I am newish to zoom when hosting meetings with two co-hosts to more than 50 people.

I want to hide myself when I have my co-host talk and present her/her slides.

Is there a simple way to do this? I cannot see this in zoom.

I also want those viewing the presentation to ask questions but it seems that there is no Q and A with Zoom Pro.

I have Zoom Pro.
