Let's try this way, when using querySelectorAll() to select elements and then attempting to access them with dot notation (.) or to access their classes, you may not receive IntelliSense suggestions for the DOM element's properties or methods. This might happen because querySelectorAll() returns a NodeList, which is not an array and doesn't automatically grant access to the properties and methods of DOM elements.

To get full IntelliSense on the DOM elements selected with querySelectorAll(), you can do the following:

Convert the NodeList into an array:

const elements = document.querySelectorAll('.your-selector');
const elementArray = Array.from(elements);

Now, you can access the elements in the array and get full IntelliSense:

// Access the first element in the array
const firstElement = elementArray[0];

// Now IntelliSense should suggest properties and methods of the DOM element:
firstElement.textContent = 'New text'; // Example of using a property
firstElement.classList.add('new-class'); // Example of using a method

The key is to convert the NodeList into an array so that you can access the elements as if they were array elements and, as a result, receive full IntelliSense. Let me know how with this if it works.
