I tried to install opencv and I'm getting this error: TypeError: Cannot set properties of undefined (setting 'cv').

I already configured webpack:

const nextConfig = {
    webpack: (config) => {
        config.resolve.fallback = { fs: false, path:false, "crypto": false  };
        return config;
    },
};

And this is how I import it:

"use client"
import cv from "@techstark/opencv-js"
export default function Home() {
  return (
    <div onClick={() => {
      console.log(cv)
    }} className="">
      CLICK
    </div>
  );
}

What am I doing wrong?
