title: RESOURCE_EXHAUSTED error when making requests to the Google Assistant API
body: <p>After some time playing with the Google Assistant SDK, I start getting this error:</p>
  
  <pre><code>grpc._channel._Rendezvous: &lt;_Rendezvous of RPC that terminated with 
  (StatusCode.RESOURCE_EXHAUSTED, Insufficient tokens for quota 
  'ConverseGroup' and limit 'DailyLimit' of service 
  'embeddedassistant.googleapis.com' for consumer 'project_number:
  &lt;REDACTED&gt;'.)&gt;
  </code></pre>
  
  <p>What does this mean and how can I resolve this?</p>
