How to properly install a custom APO (Audio Processing Object) for a WinUI 3 Desktop application?

Question

I’m working on a WinUI 3 Desktop application that requires a custom Audio Processing Object (APO) to provide a specialized audio effect. However, I’m not entirely sure how to properly install and register an APO for a WinUI 3 Desktop app so that it’s recognized by the Windows audio subsystem, and also updated or uninstalled when necessary.

If anyone has experience deploying custom APOs with WinUI 3 or references to relevant docs/samples, I would really appreciate any guidance on the recommended setup and best practices. Thank you!
