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)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraScript : MonoBehaviour
{
    // Start is called before the first frame update
    void OnDrawGizmos()
    {
        float verticalHeightSeen = GetComponent<Camera>().orthographicSize * 2.0f;
        float verticalWidthSeen = verticalHeightSeen * GetComponent<Camera>().aspect;


        Gizmos.color = Color.gray;
        Gizmos.DrawWireCube(transform.position, new Vector3(verticalWidthSeen,verticalHeightSeen,0));
    }
}
