  <h3>Examples</h3>

  <p>If you want to subscribe to <code>onParticipantsChanged</code> or <code>onLiveLocation</code>, send the request with only the <code>chatId</code> and 
    it will subscribe for those events on that chat. The output <code>msg</code> contain also a property <code>chatId</code> with the id of the chat that has emitted the event</p>

  <p>Function node code for calling <code>sendMessageToId</code> API:</p>
  <code>
    msg.payload = { topic: 'sendMessageToId', payload: [ 'xxxxxxxxxxxx@c.us', 'Hello from Node-Red'] }
    return msg
  </code>

  <p>Result of previous message:</p>
  <code>
    { topic: 'sendMessageToId', payload: [ 'true_xxxxxxxxxx@c.us_xxxxxxxxxxxx' ], origin: { //the origin message request } }
  </code>

 <p>Output for an <code>onMessage</code> event:</p>
 <code>
  { topic: 'onMessage', payload: [ { // the message object } ] }
 </code>
