title: Sending messages from Sender to Custom Receiver with Chromecast receiver API V2
body: <p>I've looked high and low for an answer and I can't seem to find anything, <a href="https://developers.google.com/cast/docs/custom_receiver" rel="noreferrer">Google's Docs</a> seem incomplete to the matter of message sending to a Custom Receiver.</p>
  
  <p>Also previous answers on StackOverflow seem to only be using the V1 Receiver API which don't seem to work with the V2 API.</p>
  
  <p>Could anybody point me in the right direction to simply explain how to send a message from a Chrome Sender App to a Receiver using the V2 API? </p>
