Detecting laser pointer hovering on button (Oculus Quest - Unity3D)

I have a Unity scene with a VR interface composed by a Canvas (World Space coordinates) and two buttons. The canvas has attached an OVR Raycaster objects which uses a laser pointer. Overall it works well, but when I try to intercept the event produced by hovering the laser pointer on the button, I can get only the click event.

I'm using the following script (attached to the button):

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
public class VRButton : MonoBehaviour, IPointerEnterHandler, IPointerClickHandler, ISelectHandler
{
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{

}

public void OnPointerEnter(PointerEventData eventData)
{
Debug.Log("Enter!");
transform.localScale *= 1.2f;
}

public void OnPointerExit(PointerEventData eventData)
{
Debug.Log("Exit!");
transform.localScale /= 1.2f;
}

public void OnPointerClick(PointerEventData eventData)
{
Debug.Log("Clicked!");
}
}

The strange thing is that both OnPointerEnter and OnPointerClick get called when I point the button with the laser and click. Just hovering the doesn't trigger any event (nor OnPointerExit or OnPointerEnter).

This is my ADB log:

How can I fix it?

I had the same problem and solved it.
I wrote an article in Japanese, so please translate it.
