Using Airplay 2 "Now Playing" controls from macbook air

We just bought a macbook air and we have apple tv's in every room.

We normally control the apple tv's via the remote app and Now Playing controls in control center on our iphones and ipad's. How can I use these controls on my mac?

I would like to see what is playing on the apple tv in my living room or family room, I would like to control the volume of the stereo homepods connected to my living room apple tv as speakers. I would like to play and pause shows from my mac.

How can I do this? I already know that I can open the Home app on my mac and use that to play and pause but I cannot control the volume easily.

Do you have a control center style "Now Playing" available as a widget or something else for my macbook air?
