Access checker feature coming to Google Slides

Access checker is a feature in Gmail and Google Chat that ensures the recipients of a Drive file have permissions to access it. This feature is now coming to Google Slides, to make sure that anyone who is viewing or presenting a Slides presentation can play embedded videos and audio files. 

When you insert a video or audio file (external link)  that is stored in Drive into Slides, Access checker will automatically look to see if the people who have access to the presentation also have access to the audio or video file you just inserted. If they don’t, Access checker will suggest changing the permissions for the audio or video file so that all viewers, commenters, editors, and owners of the presentation will be able to see and hear its content. If more users are given access to the Google Slides, the editor of the slides will have to re-share the video or audio file with the new users. Google is working towards updating the access checker to a perform an access check for all Drive video and audio files in the presentation after you share the presentation with additional users.
