airplay screen mirror specific device via keyboard shortcut

hello, I hope his is the correct place to ask this

I have an Apple TV 4k in one room and a 2012 Mac mini running Catalina in another room

I would like to use a wireless keyboard to initiate airplay mirroring so I don't have to go in to the room that the mini is in

I tried using the built in action but it only tries the first apple tv in the list which belongs to the upstairs neighbor

is there a way I can make a keyboard shortcut to initiate airplay mirroring to a specific device?

thanks in advance!
