Snapmaker Luban 3.9 on Linux doesn't list Materials

I just got my Snapmaker A350 assembled for 3D printing, today. I was going to use Snapmaker Luban 3.9, but it doesn’t list anything under “Materials,” “Printing Settings,” or “Actions.” Where do I download the settings from so that I can set PLA as the material being printed?

I used my wife’s computer with Win10, to print benchy, but I’d rather use my own.

Other people are having issues with 3.9 - try installing 3.8 maybe?
