Is it possible on youtube to track whether the user clicked the play button through the extension?

Question

JavaScript

Is it possible to track on the youtube website whether the user clicked the play button through the extension, or by the button to find out if the channel is subscribed or liked?

Answer 1

if(document.querySelector('.ytd-subscribe-button-renderer').textContent === 'Вы подписаны'){
console.log('Подписан');
}

And about tracking playback, you can try to hang a click event on the ytp-play-button class

var elem = document.querySelector('.ytp-play-button');
elem.addEventListener("click", function() {
    console.log('Нажал play');
  });
