AddEventListener弹出窗口在IE 11中不起作用

您好，我是javascript新手，我在代码中使用es6。

[基本上，我在IE中遇到addEventListener的问题，这个想法是，当我们单击图像时，会弹出一个窗口，说明它在chrome上有效，但在IE中不起作用。我知道已经有与此相关的主题，例如：addEventListener in Internet Explorer

我尝试实现此功能，但似乎无法正常工作，我想我需要了解更多如何实现与我的代码相关的功能，如果有人可以提供帮助，我将非常感谢。

const toggleButton = document.querySelector('.jsModalToggle');
    const container = document.querySelector('.modal-yt-container');

    toggleButton.addEventListener('click', _ => {
        document.body.classList.add('modal-yt-is-open')
    })

    container.addEventListener('click', e => {
        if (!e.target.closest('.modal-yt-video')) {
            document.body.classList.remove('modal-yt-is-open')
        }
    })
