title: Is there no Google Player API for Google Slides?
body: <p>We have a ruby on rails learning app. We have imported various Google Slides presentations using embed code. We are aware an API exists with a Ruby Gem to create/import slides within our APP (<a href="https://developers.google.com/slides/" rel="nofollow noreferrer">https://developers.google.com/slides/</a>)</p>
  
  <p>But we need greater control over the slides. Is there no Google Player API ? We need to detect start and stop points essentially. This will help us set a completion flag and also show and hide our player buttons. Otherwise the user will see our player buttons and the google player buttons... It seems other people have similar issues and need more control over the player aspects as I've seen similar posts. Please help!!!</p>
