title: How to manage log in session through headless chrome?
body: <p>I want to create a scraper that:</p>
  <ol>
  <li>opens a headless browser,</li>
  <li>goes to a <a href="https://cs.money/" rel="noreferrer">url</a>,</li>
  <li>logs in (there is steam oauth),</li>
  <li>fills some inputs,</li>
  <li>and clicks 2 buttons.</li>
  </ol>
  <p>My problem is that every new instance of headless browser clears my login session, and then I need to login again and again...</p>
  <p><strong>How to save it through instances?</strong> (using puppeteer with headless chrome)</p>
  <p>Or <strong>how can I open already logged in chrome headless instance?</strong> (if I have already logged in in my main chrome window)</p>
