title: Set a cookie in playwright
body: <p>I have a pop up &quot;Do you agree to Cookies&quot; window on a site I am testing and I need to bypass this, the best way I have found out is to insert a cookie beforehand, but I cannot find out how to do this on Playwright - I have done some searching around but can't find a definitive answer for what i am after, essentially the cookie just needs to fire before the URL is hit so the scream doesn't appear.</p>
  <p>Playwright cannot see the frame unfortunatley, otherwise I would just click it..</p>
