How to use the whatwg-url.percentDecode function in whatwg-url

exports.evaluateJavaScriptURL = (window, urlRecord) => {
  const urlString = whatwgURL.serializeURL(urlRecord);
  const scriptSource = whatwgURL.percentDecode(Buffer.from(urlString)).toString();
  if (window._runScripts === "dangerously") {
    try {
      return window.eval(scriptSource);
    } catch (e) {
      reportException(window, e, urlString);
    }
  }
  return undefined;
};
