Automatically switch Touch Bar to function keys for Minecraft only

Under System Preferences → Keyboard → Shortcuts → Function Keys, you can register apps to always show the function keys on the Touch Bar. I want to add Minecraft. However, Minecraft has an unusual structure where the app is actually just a launcher, then you hit a button and it opens the game in a Java window. That means the function keys then show up in the launcher, but not the game proper. I’ve tried adding the “java” executable to the function keys list by right clicking it while running, selecting Options → Show in Finder, then both dragging and dropping that file into the window and navigating to it from the Function Keys window, but in both cases the GUI didn’t accept the file to be added to Function Keys list. macOS version: 13.4 Minecraft version: 1.19.4
