Module '"bitchute-dl"' has no exported member 'isBitchuteLink'

I'm trying to use this package in my component: https://github.com/EnzoAlbornoz/bitchute-dl#readme

I'm importing it like this:

import { isBitchuteLink } from 'bitchute-dl';

But I get an error saying:

Module '"bitchute-dl"' has no exported member 'isBitchuteLink'.

Am I importing this wrong or is there a problem with the package?
