title: Create a har file with xhr request only in chrome dev tools
body: <p>Is there a way to create a <code>har</code> file with <code>xhr</code> request only in chrome dev tools?</p>
  
  <p>Even though I can filter the requests in dev tools, when I save it as a har file, it contains all the requests.</p>
  
  <p>If the dev devtools doesn't support that, is there a alternative way to do this?</p>
