title: How to get Bundle ID of Mac application?
body: <p>I want to use Python and <code>atomac</code> module to trigger an application in macOS like following scripts:</p>
  
  <pre><code>atomac.launchAppByBundleID()
  app_win = atomac.getAppRefByBundleId(app_bundle_ID)
  </code></pre>
  
  <p>But I don't know how to get the Bundle ID (<code>app_bundle_ID</code>) of the application.</p>
