Using ZXing.Net to read or create QR codes in a Godot project

I’m planning to make custom levels sharable via a QR code. Since Godot doesn’t come with QR code related features, I thought ZXing.net, a C# package, was my best bet. Setting it up was not easy, but thanks to a helpful community, I managed to get it ready to go.

However, I have no idea how to pass images between GDScript and C#. The class Bitmap (presumably System.Drawing.Bitmap, according to a Reddit commenter) used in the C# snippet came up as unrecognized. I don’t know where to start looking for a solution.
