title: Auto allow webcam access using Puppeteer for Node.js
body: <p>I'm setting up a test that involves starting a webcam video session. </p>
  
  <p>So far all is working fine and doesn't require any user interaction except for granting access to the webcam.</p>
  
  <p>When the third party library I'm using makes the call: <code>navigator.mediaDevices.getUserMedia({audio: true, video: true})</code>
  the browser opens a prompt asking the user to allow access. </p>
  
  <p>What I'm looking for is a way to grant access without user interaction. </p>
  
  <p>I've tried puppeteer's <code>page.on('dialog'...</code> but that doesn't get called for the webcam access prompt.</p>
  
  <p>Please let me know if you have any ideas?</p>
