Webinar: How can we automatically spotlight with gallery

Just to clarify.  The screen capture above is what we want, with the person in the large image always being the person who is speaking.  

By default, anyone who speaks is automatically spotlighted, no need to do anything else except to tell others maybe to shut up or simply mute them until it is their turn. 

But you can also force the spotlight to other panelists if you want. But I would advise to keep it simple initially, and do a lot of testing, so you and your participants will have an idea of what to expect.

Thank you ZzZz for your response.  I want the speaker to be highlighted and I want them to appear large and centered in the window, rather than in the gallery.  Is that possible?
