title: Google Pub/Sub emulator: Get unacknowledged messages?
body: <p>I'm using version 368.0.0 of the Google Pub/Sub emulator. I like to get the currently unacknowledged messages - at least their number. Preferably also their content and other meta-data.</p>
  <p>How do I do that?</p>
  <p>I can successfully ran requests to e.g. <code>http://localhost:8123/v1/projects/my-project/topics</code>, but I cannot find any endpoint for listing  unacknowledged messages on <a href="https://cloud.google.com/pubsub/docs/reference/rest" rel="nofollow noreferrer">https://cloud.google.com/pubsub/docs/reference/rest</a>.</p>
  <p>According to <a href="https://stackoverflow.com/questions/52638114/rest-api-for-monitoring-undelivered-message-in-google-cloud-pubsub">the answer on this question</a> I'd have to use a different API. However, I did not find out how to access that API on the emulator</p>
