Currently, it's only possible to snap to features added to mapbox-gl-draw. add as in Draw.add or Draw.set.
I assume you can add features currently available to the viewport to Draw as well to get the snap behavior.

I'm looking for this too, I wonder if it's possible to add the existing polygons to Draw but make them readonly as I don't want them to be editable, just used in snapping considerations.

One possibility: https://stackoverflow.com/a/66009522/241465

This would be a nice feature but I can see how implementing it would be tricky. I have a giant layer (sidewalk data for a region) that would be nice to snap to, but unwieldy to move into Draw.

+1 on this, would be a very useful feature to list out the sources or layers that new features should be snapped to.
