The Problem

I am trying to create a userscript to unpause the video when I change the tab to listen to music etc because, whenever I change the tab the video pauses itself on m.youtube.com (mobile version of youtube)

I have tried to look around the web to find any possible solutions like turning off browser flags but none of it seems to work.

Current Code

document.addEventListener("visibilitychange", event => {
  if (document.visibilityState == "visible") {
    console.log("tab is active")
  } else {
    var ytplayer = document.getElementById("movie_player"); // get youtube player
    ytplayer.playVideo(); // play it when tab inactive
  }
})

Userscript extension: Tampermonkey
