Options greyed out in Windows 10

[silverscampi]

Hello,
These are the steps I took:

I am using Windows 10 build 19041.
I uninstalled any previous version of Inkscape and Python I had, just in case.
I installed the latest Python 3.9.5 (64-bit) for Windows.
I installed Inkscape 1.0.1 (64-bit) as it seems to be the latest one which should work with this extension.

I then restarted for good measure...
I downloaded 4xiDraw release v1.2.2 from here, unzipped it and put the contents (4xidraw-1.2.2/) into the Inkscape user extensions folder.

I restarted again for good measure...
Plugged in the 4xiDraw, checked in Arduino IDE serial monitor to see it was indeed connected and responded to commands.
Closed Arduino IDE and serial monitor so as not to interfere.

Launched Inkscape 1.0.1.

The 4xiDraw extension is there, but the 'AxiDraw Control' and 'Hatch fill...' options are greyed out.

(A similar issue was posted but it seemed as if an older release was used)

Do you have any advice?
Thank you!

Nevermind, I was in a hurry and did not read the readme in full... I installed "as you would any other Inkscape extension" but missed the part where the driver files must be put in the extensions folder outside of the 4xidraw folder.
