How can I get "_U" cookie from bing.com?

Hi, sorry if this is a simple question.

I have a JS code to get "_U" cookie from a page. But I don't know how to use it on bing.com.

The blow is my funciton.

function getCookie() {
  const cookieName = "_U";
  const cookies = document.cookie.split(';');
  for (let i = 0; i < cookies.length; i++) {
    const cookie = cookies[i].trim();
    if (cookie.startsWith(cookieName + '=')) {
      return decodeURIComponent(cookie.substring(cookieName.length + 1));
    }
  }
  return null;
}

You don't use it on bing.com; you go to bing.com and get the _U cookie (you can grab it from DevTools), and then you give it to BingAIClient to use it.

Thank you!! By chance, is there any way to grab the key using iframe?

I think you can just grab it manually. It lasts indefinitely so you don't need to worry about refreshing it.
