title: How to use Google extensions API to launch a desktop application?
body: <p>I do not really find a google extensions API that launches a desktop application, but I see WebEx did it. <a href="https://meetings.webex.com/collabs/#/home" rel="nofollow">https://meetings.webex.com/collabs/#/home</a> Here when you host a meeting, it requires you to install the WebEx Chrome Extension. The extension then launches the desktop application. What is the magic behind it?</p>
  
  <p>Is it the technology they use? <a href="https://developer.chrome.com/extensions/nativeMessaging" rel="nofollow">https://developer.chrome.com/extensions/nativeMessaging</a>
  I see an API called "runtime.connectNative". Does it start a desktop application? </p>
  
  <p>HINT: NPAPI already expired for Chrome. So NPAPI is not what WebEx used</p>
