How do you add Ryujinx game shortcuts to a Steam collection?

I’m trying to add my Ryujinx games to Steam so I can launch them from there and organize them into a collection, but I’m stuck. When I go to “Add a Non-Steam Game” in Steam, none of the shortcuts I’ve already made for my games show up in the list. I’m not sure if I’m doing something wrong or if Steam just doesn’t detect them that way. Has anyone here successfully added individual Ryujinx games to Steam? Do you add the emulator itself, or is there a way to add each game separately? If you’ve gotten this working, could you explain how you set it up (like launch options, paths, etc.)? Appreciate any help 🙏
