How to destroy instantiated button upon collision exit - Unity 3D

I am a beginner in Unity and I am currently making a simple game. I have a problem where the instantiated Button is not destroyed.

The process of the script is to instantiate a button and destroy it upon collision exit. But when I move out of the object, the object stays and it is not destroyed. i don't know if there is something wrong with the Destroy code of line.

Here is the script for the collision:

using UnityEngine;
using UnityEngine.UI;

public class InteractButtonPosition : MonoBehaviour
{

    public Button UI;
    private Button uiUse;
    private Vector3 offset = new Vector3(0, 0.5f, 0);
    // Start is called before the first frame update
    void Start()
    {
        //uiUse = Instantiate(UI, FindObjectOfType<Canvas>().transform).GetComponent<Button>();
    }

    // Update is called once per frame
    void Update()
    {
        //uiUse.transform.position = Camera.main.WorldToScreenPoint(this.transform.position + offset);
    }

    private void OnCollisionEnter(Collision collisionInfo)
    {
        if(collisionInfo.collider.name == "Player")
        {
            uiUse = Instantiate(UI, FindObjectOfType<Canvas>().transform).GetComponent<Button>();
            uiUse.gameObject.SetActive(true);
            uiUse.transform.position = Camera.main.WorldToScreenPoint(this.transform.position + offset);
        }
    }

    private void OnCollisionExit(Collision collisionInfo)
    {
        if(collisionInfo.collider.name == "Player")
        {
            Destroy(uiUse);
        }
    }
        
}
