You can use legacy Borderless Gaming (not the Steam Version, why would this even be on Steam) here to make it work seamlessly with no setup blah blah blah: https://legacy.borderlessgam.ing/

Run the game and move it to the right, and as long as it's open in your system tray it'll fullscreen automagically on open.
Anyway, if this is spyware... not sorry! Good luck.
