I'm trying to get my extension to automatically change all content with "views" into "Views hidden" and something similar for "watching" (live streams), but when I run the extension it seems to do nothing. I'm thinking it might have something to do with me not knowing the permissions required or some other thing, but I can't seem to figure it out. This is my first time using javascript.

manifest.json

{"manifest_version": 2,
    "name": "SimplyWatch",
    "description": "Simply watch YouTube videos without any views, comments, or ratings data displayed for an experience unbiased by others' opinions.",
    "version": "1.0",
    "author": "Diamivore",
    "browser_action": {
        "default_icon": "tab-icon.png",
        "default_title": "SimplyWatch",
        "default_popup": "popup.html"
    },
    "permissions": ["activeTab", "tabs"],

    "content_scripts": [
        {
            "matches": ["<all_urls>"],
            "js": ["content.js"]
        }
    ]
}

content.js

const text = document.querySelectorAll('h1, h2, h3, h4, h5, p, li, td, caption, a, span')

document.addEventListener("DOMContentLoaded", function(){
    for (let i=0; i < text.length; i++) {
        if (text[i].innerHTML.includes('views')) {
            text[i].innerHTML = "Views hidden"
        } else if (text[i].innerHTML.includes('watching')) {
            text[i].innerHTML = "Watchers hidden"
        }
    }
});

Any help?
