I just looked at the svg’s, and they are rubbish. He just imported the BB svg into another part - this is usually how you make parts -, but never bothered doing the other views. Basically you would have to start with that BB svg, make the PCB svg, and SCH svg, import those svg’s into a part with FZ Editor, and assign pins. If you don’t need the other views, you just need to put the BB svg into a part and assign pins. It a fair amount of work, especially if you don’t know how, but maybe watch these tutorials and then decide if you want to tackle it or maybe wait and see if Vanepp can do it.
Vanepp did a text guide, but I can’t find it so you will have to look for it.
