How do I create a scene view in an editor window WITH the gizmo activated ?

Hello, I am trying to create an editor window with a scene view in it. The problem I got, is that it render it in game mode and I want it to show it like in the scene view with the gizmo. I tried the following code, but it only renders in game mode.

 using UnityEngine;
 using UnityEditor;
 
 public class TestWindow : EditorWindow
 {
 
     public Camera m_Cam = Camera.main;
     private Rect sceneRect;
 
     [MenuItem("Test/TestWindow")]
     static void Init()
     {
         TestWindow window = (TestWindow)EditorWindow.GetWindow(typeof(TestWindow));
         window.autoRepaintOnSceneChange = true;
         window.Show();
     }
 
     void OnGUI()
     {
 
         // important: only render during the repaint event
         if (Event.current.type == EventType.Repaint)
         {
             sceneRect = new Rect(new Vector2(10f,0f), new Vector2(100f,100f));
 
             m_Cam.pixelRect = sceneRect;
             m_Cam.cameraType = CameraType.SceneView;
 
             m_Cam.Render(); // render the camera into the window
         }
     }
 
 }

To be specific, I want to be able to see the colliders bound around an object that I would show in that editor window.
