there are a few options to make gog/epic games works with heroic, if it doesn’t work out of the box :

• using proton from steam/GE
• using steam runtime
• using protondb to know what to tweak the launch options or windows component to download via wine tricks
• copy the game in steam.

I’ve seen that a protondb user posted about cyberpunk 2077 working on heroic launcher. I hope you’ll manage to have it too.
