Game Center custom leaderboard icons with dark mode

I'm working on adding iOS 13 dark mode support to my app, and ran into an issue with updating my custom Game Center leaderboard/achievement icons. See a screenshot here.


What I'd like is to be able to provide a different icon asset for dark mode vs light mode. Is this possible?


If not it seems like the only other option is to redo all the icons to look decent in both light and dark mode, but I don't see a design that will achieve this without clashing with the minimalistic design of the rest of the app...
