Using QuerySelector for nested elements

Need to change the text of nested HTML element with specific class names and thought this was a good use of document.querySelector. This way I can use CSS type selectors to find the element and then modify the text as needed

Example: I have the following

<div class="level1">
  <h2 class="specialLabel">Text to Change</h2>

Now I want to change h2 Text to Change to say Change for the better and to be clear there are numerous other divs and h2 in this div that I am not showing for brevity.


    window.addEventListener("load", (event) => {
      const titleElement = document.querySelector("div.level1 h2.specialLabel");
      if (titleElement !== null) {
          titleElement.innerText = "Change for the better";
