title: How can I use custom slash commands within threads in Slack
body: <p>I've setup a custom slash commands <code>/news</code> witihn slack and it works fine but I can't find a way to use trigger slash commands via threads.</p>
  <p>I get the following error: <code> /news is not supported in threads. Sorry!</code></p>
  <p>i've looked through the slack api documentation and i can't seem to find it. I know its possible because I have the <code>/giphy</code> app installed and I can use that in threads.</p>
  <p>I found this article but it was not really helpful.
