Registering a macOS app for dynamic text sizing in macOS 15

macOS 15 includes a neat section in System Preferences Settings to change the dynamic text size, as outlined see: https://support.apple.com/guide/mac-help/make-text-and-icons-bigger-mchld786f2cd/mac

However, it's not immediately clear a) how to get one's app in this list, and b) if the usual methods from iOS to react to text size even work on macOS. Does anyone have any experience here? Or should I implement my own controls in my app's settings and call it a day?

For context, my app is a macOS-native SwiftUI app.

As the text on that sheet says, the option is only the apps listed there.

Maybe it will be expanded to third party apps in the future, who knows.
