Need help loading Kate script on Windows 10

Hi,

I've written a script which loads and works fine in Kate on Linux Mint, but
I haven't been able to load it in Kate on Windows 10.  I'm using the
instructions here:
https://docs.kde.org/stable5/en/kate/katepart/dev-scripting.html

On Linux Mint I put the script here:
  ~/.local/share/katepart5/script/commands/.
and that works.

On Windows 10 I put the script here:
 %USERPROFILE%\AppData\Local\katepart5\commands\.
and I can't see the script in Kate after restarting Kate or running the
reload-scripts command.

To complicate things, these are using two different versions of Kate:
1. Latest from apt repository in Linux Mint:
Kate Version 19.12.3
KDE Frameworks 5.68.0
Qt 5.12.8
Kate Part 5.68.0
2. Latest from Microsoft Store:
Kate Version 21.12.0
KDE Frameworks 5.88.0
Qt 5.15.2
Kate Part ?

Can any of you tell me how to get the script to load on Windows 10, or help
me to troubleshoot this problem?

You can find the script "clipboard_append.js" here:
