How to track on YouTube through js whether a person has put like, dislike and nothing at all?

Question

JavaScript

What's the question ?
I have an extension, I want to track through javascript whether a person likes, dislikes or nothing at all on a video, in general, somehow track whether he somehow rated the video.
I was told in the last question that it is possible like this.

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

But the whole problem is that it will work if the YouTube interface is in Russian.
That is, it will be necessary to take textContent and run the word subscription or unsubscribed through cycles in different languages ​​and then draw conclusions.
Maybe there is some other way?
Of course, I tried to do something yesterday, but attempts to do it did not lead to anything.

document.querySelector('.ytd-toggle-button-renderer').textContent;

The whole problem is that there are a bunch of these buttons with the .ytd-toggle-button-renderer class and there is no such simplicity as with the subscribe button.
One more thing worries what are these tags for Google in the house?
Did they write a bunch of their tags?
How to learn to work with them in general, that's what I need.
Understand whether there is a subscription or not, evaluate the video, track what the video is currently playing and when it is paused.
