Display 2D Unity camera frame

When the camera is not selected, there is no frame. When selected, there is a frame. Gizmo is on. I just created a new project, didn't touch anything else

 

The problem was solved by imposing a script on the camera (one guy helped me)

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CameraScript : MonoBehaviour
6. {
7.     // Start is called before the first frame update
8.     void OnDrawGizmos()
9.     {
10.         float verticalHeightSeen = GetComponent<Camera>().orthographicSize * 2.0f;
11.         float verticalWidthSeen = verticalHeightSeen * GetComponent<Camera>().aspect;
12.  
13.  
14.         Gizmos.color = Color.gray;
15.         Gizmos.DrawWireCube(transform.position, new Vector3(verticalWidthSeen,verticalHeightSeen,0));
16.     }
17. }
