I'm making a small app for myself to change the desktop background image periodically.

My program contains this block of code:

```
let screen = NSScreen.main()!
let newWallpaperURL = URL(/* ... */)
// ...
try! NSWorkspace.shared().setDesktopImageURL(newWallpaperURL, for: screen, options: [:])

```

This works, but only for the current "space" the keyboard is focused on.

e.g. if I'm in a fullscreen app, only the background of the Space occupied fullscreen app will be changed (not the background of my normal desktop).
If I have two Spaces/desktops, it only changes the background image of one of them.

Is it possible to individually set wallpapers for each space programmatically?
