const hooker = new FunctionHooker();
hooker.hook('window.addEventListener', (...args) =>
{
const dissallowedEvents = ["pagehide"]
if (dissallowedEvents.includes(args[0])) return;
// gets the unhooked original function if you need to call it in the hook
const o = hooker.getOriginal("window.addEventListener");
// addEventListener only has either 2 or 3 arguments
if (args.length == 3) o(args[0], args[1], args[2]);
else if (args.length == 2) o(args[0], args[1]);
});
