I don't think it's a dumb question and I don't fully have the answer. I know Lutris seems to be massively more customizable to get games running. You have runner scripts created by the community as well.

At this point though I've added games to Steam as a non-steam game and it works when I couldn't get it working via Lutris. I've basically given up on Lutris personally and just use Heroic for GOG and Epic games and Steam for everything else.
