Question How do you access a Rich text link tag in a Label element?

So UI toolkit supports Rich text now and you can format text using tags.

But how would you implement something like this which works for a standard Text Mesh Pro component
to find out when the mouse is over a link tag?
I can register an event to get when the mouse is over the whole label but I want a particular word.

Code (CSharp):

1. using UnityEngine;
2. using TMPro;
3. using UnityEngine.EventSystems;
4.  
5.  
6. [RequireComponent(typeof(TMP_Text))]
7. public class OpenHyperlink : MonoBehaviour, IPointerClickHandler
8. {
9.     private TMP_Text m_textMeshPro;
10.     void Start()
11.     {
12.         m_textMeshPro = GetComponent<TMP_Text>();
13.     }
14.     public void OnPointerClick(PointerEventData eventData)
15.     {
16.  
17.         int linkIndex = TMP_TextUtilities.FindIntersectingLink(m_textMeshPro, Input.mousePosition, null);
18.         if (linkIndex != -1)
19.         {
20.             TMP_LinkInfo linkInfo = m_textMeshPro.textInfo.linkInfo[linkIndex];
21.             Application.OpenURL(linkInfo.GetLinkID());
22.         }
23.     }
24. }
