title: Post data with Chrome Custom Tabs
body: <p>Is there a way to send post data with url with Custom Chrome Tabs? Like it was with WebView:</p>
  
  <pre><code>webView.postUrl(String url, byte[] postData)
  </code></pre>
  
  <p>Cannot find any about it in <a href="https://developer.chrome.com/multidevice/android/customtabs" rel="noreferrer">documentation</a> or in <a href="https://github.com/GoogleChrome/custom-tabs-client" rel="noreferrer">examples</a></p>
