Extension support on all websites

[LEVAAP]

I'm making a extension right now that will pause every video playing on tab focus. But I'm struggling with the permissions object in the manifest.json. I tried everything to make the extension work on every page on the internet: "<all_urls>" and "http:///" and "https:///" and "tabs" Why does nothing work? (Except for "tabs", that didn't gave problems, but it don't read a VideoElement on a webpage) and what should I use now? Btw I use manifest version 3 and try to make it work in Opera GX.
I visited the developers page of Opera GX and it said "<all_urls>" would do the job but that gave me just a error when trying to unpack it.

{
  "manifest_version": 3,
  "name": "Mijn extensie",
  "description": "Dit is mijn extensie",
  "version": "1.0",
  "background": {
    "service_worker": "background.js"
  },
  "host_permissions": [<all_urls>],
  "content_scripts": [
    {
      "matches": ["*://*/*"],
      "js": ["background.js"]
    }
  ]
}

I'm assuming you're saying that using "matches": ["*://*/*"] fixed the problem?
