It seems not to match types.
I've seen the library, the repo don't seem have any types at all, you can force them by copying the last two lines from the screenshot you've shared.

To keep it easy to use I recommend doing that in a separate file and exporting the same name, this way you can use them seamlessly from the original library in the whole project.
