问如何捕获Chrome扩展中confirm()弹出窗口的响应？

EN

const eventId = chrome.runtime.id;
addEventListener(eventId, e => {
  console.log('Intercepted confirm:', e.detail);
  // do something with the result right here inside the listener
})
runInPage(fn, eventId);

function runInPage(fn, args) {
  const script = document.createElement('script');
  script.textContent = `(${fn})(${JSON.stringify(args).slice(1, -1)})`;
  document.documentElement.appendChild(script);
  script.remove();
}

function hookConfirm(eventId) {
  const { confirm } = window;
  window.confirm = (...args) => {
    const res = confirm.apply(window, args);
    dispatchEvent(eventId, new CustomEvent(eventId, {detail: res}));
    return res;
  };
}
