How does touch work in BanjleJS

That is helpful, but what i'm looking for is a little lower level.

So here's where the underlining code gets called to handle touch events

It gets called here. But this can only be reached by the bangle2 watch.

Here is where the bangle 1 gets its touch events from

So i know there's a few other watches that are supported with bangleJS and they have touch screens. So i'm curious how do they get there touch events. Since both of these touch event handlers are covered in defines that only work for the bangle watches.
