I'm building a simple app for Tizen OS Smart TVs. The app has to contain one main element: a video player. I've already build it for WebOS and it works fine, while I noticed that in TizenOS the video player hide the "fullscreen button". I searched in the Tized Docs end found this example: https://docs.tizen.org/application/web/guides/w3c/supplement/fullscreen/ I tried to implement the "Toggle fullscreen video" button but it doesn't work, I hope to be near the solution... Here's the entire code: Mitology TV
