Can't use the Cura script on Cura for Linux (Appimage version)

[ColdBeer72]

Hi! I tried copying the fastGyroidInfill.py file to the folders:
$HOME/.config/cura/5.2/scripts/fastGyroidInfill.py
$HOME.local/share/cura/5.2/scripts/fastGyroidInfill.py
No way to find it on PostProccessing menu with both places.
Just a few lines in cura.log:

NOTE (FYI): both folders works for the plugin and let the same lines in log file.
