You shouldnt be fetching a file url like that as:
- this forces people to need internet for this extension to work
- url could go down at any point
You should use a data.uri instead.
Also add /* global [library name here] */ to fix the lint errors

the desktop app still needs to work without internet (this is why the extension library there can only update when the app does, because it's stored offline).
for importing, i think using await import() and making the extension function async is a simple option (and probably also add /+esm to the jsdelivr url so that you can access the library from import()'s return value without adding stuff to the global scope), but you should still make the extension url a data url because of the offline part
