title: Slack create custom embedded video or audio player... similar to the Youtube integration
body: <p>Is it possible to create a custom website integration with Slack, similar to what Youtube has done? I have a webpage that consists of a standalone media player. I'd like Slack users to be able to use my media player directly within a slack convo when a link to my media player has been shared, similar to what Youtube has done. I don't want to force users to leave the conversation by going to a separate browser window.</p>
  
  <p>Is this possible?</p>
  
  <p>Here is an example of what I'm looking to do for my custom media player:</p>
