Handling User Interaction

I just started learning swift today and Im trying to create a stopwatch app that'll allow you to click one of the physical buttons on the watch and not the screen for an easier timing experience. I read a few things saying that apple doesn't allow the digital crown to be manipulated within your code but is it the same for the side button as well?

Any help would be greatly appreciated thanks.
There is a WKCrownSequencer that allows to track rotation of the digital crown.

But, AFAIK, it does not allow to intercept the click.
The reason is probably that click is used by system to detect you want to leave the app and that behaviour should remain consistent.
Thanks
