`kns` URL scheme for themes that should install to `kwin/decorations`?

I made a theme package of window decorations (Pling id: 2355039), it uses Aurorae’s QML API, not in SVG file, and according to corresponding source code this type of theme exists under kwin/decorations.

I investigated /usr/share/knsrcfiles but didn’t find any clue here, however I wish users can install this theme as a dependency of Global Theme. What shoud I do?

It seems like this theme type is under development, and its knsrc file is missing. So although I can make it works on Plasma 6, I can’t find way to distribute it on KDE Store properly.
