Ipad sharing volume

I am looking for how to control my ipad volume when I'm screen sharing.  Specifically, I'm using zoom from my iMac.  I want to share a game from my ipad, and I go to share screen - ipad (i typically use connected).  I make sure my ipad volume is down or off, but while sharing game/app with my client, the volume is so loud, that I can no longer hear them.  I have tried adjusting the volume on the ipad, on my iMac, checking the game app settings, the iPad settings.  What am I missing?  Help
