How can I render a mesh or any color in macOS lockscreen under the clock but above the desktop image? [closed]

I'm trying to simulate the iOS effect where the wallpaper darkens and changes color matching the album art of a song when the album art is expanded, I'm trying to achieve the same thing on macOS Tahoe in Swift but my key findings are that

Level 400 + delegateWindow = visible on lock screen, above clock

Level 300 + delegateWindow(toAbsoluteLevel: 300) = NOT visible

I need the (for now a red image) to render below so the default macOS clock is visible, but above the lock screen wallpaper.

Does anyone know a workaround with any private frameworks? I've seen it done in another app and I can't figure it out.
