Main Question: How to close the ad in Javascript?

I used to use a userscript on YouTube that I made that would click the skip ad button after the 5-second required time so I don’t violate YouTube’s terms.
Here is the Code:

// ==UserScript==
// @name         By Mohtady
// @namespace    http://tampermonkey.net/
// @version      2024-07-20
// @description  By Mohtady!
// @author       You
// @match        https://www.youtube.com/*
// @icon         https://www.google.com/s2/favicons?sz=64&domain=youtube.com
// @grant        none
// ==/UserScript==

(function() {
    'use strict';
    function getRandomInterval(min, max) {
        return Math.floor(Math.random() * (max - min + 1) + min);
    }

    setInterval(function() {
        let skipButton = document.getElementsByClassName("ytp-skip-ad-button");

        if (skipButton != undefined && skipButton.length > 0) {
            setTimeout(() => {
                skipButton[0].click();
                // after 5 sec
            }, 5000);
            // ad found!
        }

        console.log("Running");
    }, getRandomInterval(1000, 3000));

})();

And when I tried to run document.getElementsByClassName("button")[0].click() in the console it found the button (document.getElementsByClassName("button")[0]) but when it tried to click it, it did nothing.
Literally Nothing, no errors and it did nothing I could see on the webpage and the ad was still running.
I expected it to be an easy matter but it seems not!

Did YouTube change the way it reads button clicks?
Is anyone facing the same problem?
