如何制作改变视频播放状态的按钮?

How to make a button that changes video's playstate?

我想做一个笑话网站和我的朋友们rickroll,但我只能做一个静音自动播放的视频。所以我想制作一个假的cookie同意按钮来改变视频播放状态(基本上是一个播放视频的按钮)

function videoPlay() {
    var video = document.getElementById('myvideo');
    var btn = document.getElementById('playBtn');
    if (video.paused) {
        video.play();
        btn.innerHTML = "Pause"
    } else {
        video.pause();
        btn.innerHTML = "Play"
    }
}
<video id="myvideo" src="https://www.w3schools.com/html/mov_bbb.mp4"></video>
    <button id="playBtn" onclick="videoPlay()">Play</button>
