    // This means it will watch for elements being added or removed anywhere in the DOM.
    // We don't need to observe attributes specifically here, as we are looking for the
    // presence of the container itself.
    observer.observe(document.body, { childList: true, subtree: true });

    // Also, run the function once immediately in case the elements are already present on page load.
