    Probably you're trying to get the Element before it's even loaded on the page.

    If so, you can wrap your code into the DOMContentLoaded event:

    document.addEventListener('DOMContentLoaded', function() {
      console.log(document.getElementById(':ik').textContent);
    });
    

    But if you really want to get the element by its aria label, you can do that:

    document.querySelector('div[aria-label="Message Body"]');
    

    But this way is much less performatic, and you'll need to do exactly what I've mentioned above too.
