So recently I have been trying to set up GOG connect with my steam account but it cannot seem to detect my steam copy of DUSK. I did what it said and waited 2 hours before refreshing the page but no luck. I just clicked the browser refresh button since I couldnt find or see the other refesh icon. I even tried starting up DUSK in Steam and setting my game and profile settings to public but that didn't work either. Any other suggestions for what I should do?

If you've followed everything described here then contact support and wait since that's the last option available to you, unless you want to try playing the game through Steam again, waiting a few minutes and then revisiting the Connect page to see if it either recognizes it or hit the refresh button on the page so that it scans your account again.

I had trouble with this as well, despite having my games/profile on Steam set to public. Playing the game on Steam for a bit, then checking for available games on Connect apparently fixed it. So you might try that again.

Otherwise, yeah, try support.
