GrapheneOS compatibility to Galaxy Watch 7

Meaningbook

Hey, I'm thinking about switching over to GrapheneOS and I was wondering if there were any compatibility issues with connecting a Galaxy Watch 7? I've looked around the forum already and didn't see much other than posts saying samsung watches do work with GrapheneOS. So to those who have got it working, how'd you do it?

In general mine worked. I had to fiddle (rinse and repeat) a few times to get Samsung Pay to work, but most was pretty straight forward. There are some Samsung Health features that don't work out of the box without a Samsung phones. Most can be enabled with more fiddling (lookup SHM on XDA forum - I'm running it, and it seems reputable, but do your own due diligence).
