Question How to detect if mouse over TMP_Text sprites.

Hey there,
I'm trying to make a Tooltip system for a game. I already made a component I can attach together with TMP_Text that enables me to show tooltips when hovering words like this:

Code (CSharp):

1. //On a script attached to the TMP_Text object.
2. public void OnPointerMove(PointerEventData eventData)
3.     {
4.         int wordIndex = TMP_TextUtilities.FindIntersectingWord(text, Input.mousePosition, Camera.main);
5.      
6.         if (wordIndex != -1)
7.         {
8.             TMP_WordInfo wordInfo = text.textInfo.wordInfo[wordIndex];
9.  
10.             word = wordInfo.GetWord();
11.  
12.             //the word is used by my Tooltip system
13.         }
14.         else word = "";

I would like to do the same thing for hovering over icons that are displayed as sprites in the text.
I could not find a TMP_TextUtilities.FindIntersectingSpriteIndex(...) method or something similar that could give me any info on what if any sprite I am hovering over.

How would I go about implementing this?
I've been trying to get behind this for a few hours now but no answer I found seemed to lead anyhwere for me.
