Hey, I'm having some trouble creating a new package

I want to use this repo: https://github.com/yanivam/react-svg-worldmap and I found the files here https://unpkg.com/browse/[email protected]/dist/ And then I try to load them into http://jmmk.github.io/javascript-externs-generator/ When I load all the files and try to export WorldMap, it tells me that there is no object with that name. What am I doing wrong?
