Displaying file name of desktop wallpaper on desktop

I'm running Ventura (macOS 13.2) on an M1 MacBook Pro. I typically use five desktops (spaces). I have the desktop wallpaper on each to randomly change from a specified folder every hour. Everything works. What I'd like to do is superimpose the file name of the wallpaper image on the desktop it's being displayed on. I know this can be done, because the Particulars applet (freeware by Fraser Hess) does this, as does an older wallpaper manager, Change Desktop. I think I could use an AppleScript or Shortcut to get the file name, but I don't know how to display it (overlay) on the image. Any ideas?
