How to make a sprite character hold its two hands a two handed weapon?

Hi! Sorry but i'm completely new to unity and c# programming

How am i gonna be able to make my character hold its weapon with his two hands like this?

I have a script in right bicept that allows the right arm to follow the mouse cursor, this is the code if its needed

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class aim : MonoBehaviour
6. {
7.  
8.     public float offset;
9.     public GameObject myCharacter;
10.    
11.  
12.  
13.     void Update()
14.     {
15.         // Handles the weapon rotation
16.         Vector3 difference = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
17.         float rotZ = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
18.         transform.rotation = Quaternion.Euler(0f, 0f, rotZ + offset);
19.  
20.        
21.  
22.         if (myCharacter.transform.localScale.x == -1f)
23.         {
24.  
25.  
26.             transform.rotation = Quaternion.Euler(180, 180, rotZ + offset);
27.  
28.  
29.  
30.         }
31.     }
32. }
