Prevent Shared Screen from filling up My Zoom Window (note this is NOT about going to full screen)

Hi,

When I’m in a Zoom meeting and the host shares their screen, it automatically resizes to fill my Zoom window. I’d prefer that it not take over the entire window—especially in cases where the shared content (e.g., a YouTube video) is only being used for its audio.

Is there a way to prevent the shared screen from expanding automatically on my end? Or is this something the host can control when sharing their screen?

Thanks so much for your help!
