YouTube media playback not showing on Google Chrome on Android when used in desktop version

[Android Central Question]

I heard that we can play YouTube videos' voice when screen is locked without actually viewing the video if using the YouTube's desktop site, so when I tried it I realised that the YouTube media playback is not showing in my notification tray. I have Asus ZenPad 8.0 with Android 6.0. Will it work? I think it's because of my old Android version it's not working.
