How to use Windows icon on a messagebox

I want to use a pop-up messagebox with a Windows icon(ex. ), so I use the function "System.Windows.Forms.MessageBox.Show()".
However, it doesn't show a Windows icon but a icon that I have never seen before.

Is there anyway to change the icon back to the system's one?

Unity version: 2019.2.19f1 Project API compatibility level: .NET 4.x My code:

 using System.Collections;
 using System.Collections.Generic;
 using System.Windows.Forms;
 using UnityEngine;
 
 public class NewBehaviourScript : MonoBehaviour
 {
     // Start is called before the first frame update
     void Start()
     {
         System.Windows.Forms.Application.EnableVisualStyles();
         MessageBox.Show("Hello!","Title",System.Windows.Forms.MessageBoxButtons.OK,System.Windows.Forms.MessageBoxIcon.Warning);
         UnityEngine.Application.Quit();
     }
 
     // Update is called once per frame
     void Update()
     {
         
     }
 }
