Best method to import a QR code?

I’m having a hard time getting used to Lightburn’s method of using colors for fill instead of using a shape or path pre-determined stroke width. I’m now trying to do a vector QR code and it’s a nightmare trying to figure out which objects should be fill and which should be line. What I really want is for everything to be fill, but for it to retain the white space. The easiest method is to rasterize the vector before importing, but then I lose quality. Am I missing something or is it really this hard? Is there some other conversion process I should do beforehand to make everything into solid closed shapes before importing?
