Can Quick Actions be used on the Apple Watch to control the Keynote Remote?

Hey all.

I would like to control the Keynote Remote on my Apple Watch using Quick Actions, instead of having to tap the Watch screen. Is that possible?

Hardware: M1 MacBook Air, iPhone 14 Pro, Apple Watch 3 (with the Ultra ordered). I have no problems setting this up, so that the Apple Watch controls Keynote on the iPhone, which is running only as a remote control for the MacBook.

(As an aside, this works even while using the iPhone camera as a continuity camera for WebEx, which was a very positive surprise.)

Background: I give university lectures that take several (up to eight) hours. To keep both me and the students awake, I tend to move around and gesture a lot. So far, I use a simple bluetooth remote, which works ok, but means I always have one hand full, and also tends to blank the screen whenever I miss the correct button. Using the Apple Watch works, but to switch slides I need both hands (one to raise, one total the screen), interrupting my flow. It would be fun to be able to avoid any visible remote, switching slides with small hand gestures, but so far I have been unable to get that to work. Any tips?
