I like the feature where when someone pastes a link to an YouTube video, the client automatically embeds the video in the chat window and you can watch it right then and there.
How does that work? The reason I am asking is we have an internal video portal “similar” to YouTube but posting links to that does nothing. So is the Mattermost client recognizing the YouTube link and using some API calls to handle that embedding? Is it possible to somehow extend that functionality to handle our internal video portal site?
