Why doesn't the video play when I click the play button?

Question

YouTube

When trying to customize a video from YouTube (changing the play button + text), it was displayed in the console.
Uncaught ReferenceError: playVideo is not defined

document.getElementById("ArrowBtn").addEventListener("click", playVideo);

function arrowVideo() {
    document.getElementById("ytplayer").classList.add('block');
}

I wanted to register that when you click on my triangle, the video starts playing. The Youtube API has a playVideo function. What am I doing wrong?

Answer 1

the fact is that the playVideo function does not exist
