public class MyComponent : MonoBehaviour

    // Use UIDocument
    [SerializeField] private UIDocument _element;
    
    // Or UI Toolkit Component
    [SerializeField] private VisualElementComponent _element;
    
    // Or any UI Element
    private VisualElement _element;
    
    public void Method(VisualElement target)
    {
        // Create a Selector via the Selector Builder
        Selector selector = Selector.Builder(className: "element").Build();
        
        // Or via the Selector Parser
        Selector selector = Selector.Parse(".element");

        // Check the presence of a VisualElement that matches with the selector
        bool check = selector.Exists(_element);

        // Check if the current VisualElement matches with the selector
        bool check = selector.Match(_element, target);
    }
