Question Making of a InfoPanel for a AR Weather Application for mobile.

I'm trying to make an AR app for mobile which uses a house model to along with various assets like rain, snow, etc prefabs to portray the current weather. I need to make a panel along the side of the model to show details like the temperature, humidity, and precipitation index. This panel is not a part of the UI but the part of the 3D AR Model. So I need to be able to change the content of this panel every day. I make a prefab of a 3D - Object -> TextMeshPro and I tried to change its text by creating a cube and a sphere below it and when you tap on it, it should change the text of the prefab to either 1 or 2 respectively just for experimentation purposes. but it stayed strong to what it was by default.
I have included my code below:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6.  
7. public class Place : MonoBehaviour
8. {
9.  
10.     public Transform SpawnLoc;
11.     public GameObject SpawnObject;
12.    
13.  
14.     // Start is called before the first frame update
15.     void Start()
16.     {
17.        
18.     }
19.  
20.     // Update is called once per frame
21.     void Update()
22.     {
23.         if(Input.touchCount > 0 && Input.touches[0].phase == TouchPhase.Began)
24.         {
25.             RaycastHit hit;
26.             Ray ray = Camera.main.ScreenPointToRay(Input.touches[0].position);
27.  
28.             if(Physics.Raycast(ray, out hit, 100.0f))
29.             {
30.                 if(hit.collider.name == "Cube")
31.                 {
32.                     Text TextObj = GameObject.Find("SpawnObject").GetComponent<Text>();
33.                     TextObj.text = "1";
34.                     Instantiate(SpawnObject, SpawnLoc.position, SpawnLoc.rotation);
35.                    
36.                    
37.                 }
38.             }
39.         }
40.     }
41. }
42.  

The SpawnObject is the prefab of the TextMeshPro.


Does anybody have any ideas about how to fix this?

Thank You.
