I tried to make a speech bubble but the text always ends up bypassing the edge of the bubble ...

Hello everyone,
I recently tried to make a speech bubble by using this video of code monkey unity:

And what happened is that the text appears and everything but it always bypasses the edge of the bubble at the end.

Spoiler: Here is the code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using TMPro;
5.  
6. public class ChatBubble : MonoBehaviour
7. {
8.     public Vector2 offsetIcon = new Vector2(-2f, 0);
9.     public Vector2 paddingSize = new Vector2(2f,2f);
10.     public Vector2 PostionOffset = new Vector2(2f,2f);
11.     public float PaddingPlus =2f;
12.     private SpriteRenderer backgroundSpriteRender;
13.     private SpriteRenderer iconSpriteRender;
14.     private TextMeshPro textMeshPro;
15.     public string Text;
16.  
17.     public enum IconType {Happy,Neutrel,Angry }
18.     [Header("Icon")]
19.     [SerializeField] private Sprite HappySpriteIcon;
20.     [SerializeField] private Sprite NautrelSpriteIcon;
21.     [SerializeField] private Sprite AngrySpriteIcon;
22.     private void Awake()
23.     {
24.         backgroundSpriteRender = transform.Find("Background").GetComponent<SpriteRenderer>();
25.         iconSpriteRender = transform.Find("Icon").GetComponent<SpriteRenderer>();
26.         textMeshPro = transform.Find("Text").GetComponent<TextMeshPro>();
27.     }
28.     private void Start()
29.     {
30.     }
31.     private void FixedUpdate()
32.     {
33.         Setup(IconType.Angry,Text);
34.      
35.     }
36.     private void Setup(IconType iconType,string text)
37.     {
38.         textMeshPro.SetText(text);
39.         textMeshPro.ForceMeshUpdate();
40.        Vector2 textSize = textMeshPro.GetRenderedValues(false);
41.         Vector2 padding = paddingSize;
42.         backgroundSpriteRender.size = new Vector2
43.             (textSize.x + padding.x * PaddingPlus, textSize.y + padding.y);
44.  
45.         backgroundSpriteRender.transform.localPosition =
46.         new Vector3(backgroundSpriteRender.size.x / PostionOffset.x,PostionOffset.y) + (Vector3)offsetIcon;
47.         iconSpriteRender.sprite = GetIcon(iconType);
48.     }
49.     private Sprite GetIcon(IconType iconType)
50.     {
51.         switch (iconType)
52.         {
53.             default:
54.             case IconType.Happy: return HappySpriteIcon;
55.                 break;
56.             case IconType.Neutrel: return NautrelSpriteIcon;
57.                 break;
58.             case IconType.Angry:  return AngrySpriteIcon;
59.                 break;
60.          
61.                  
62.         }
63.     }
64. }
65.  

(Sorry for my poor English, I use Google Translate)
Please help me fast! This is very important!

 

This is the example I always start from. See attached.
