Switch roon zones

I’m using Rock and an Intel nuc running win 11 and roon to connect multichannel (hdmi) to an integra amp. I have configured a harmony remote with Windows keyboard to interact with roon eg. Next /prev track. The remote changes volume on the preamp or avr depending if i am playing stereo or multichannel. What I can’t do is change the roon zone.

I am now exploring freeware windows workflow to drive the mouse on roon windows full screen and use the keyboard function keys f1, f2, f3 etc to select the zone. Has anyone already done this?
