Particle system not active in the scene

heello everyone i want to ask a question im new to unity.

why my particles effect is not playing or is not showing when the game object collide with “Player”

thank u

using UnityEngine;

public class PointEffect : MonoBehaviour
{
    public ParticleSystem collisionEffect; // Reference to the ParticleSystem for the collision effect.

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            PlayCollisionEffect();
            
        }
    }

    private void PlayCollisionEffect()
    {
        if (collisionEffect != null)
        {
            collisionEffect.Play();
        }
    }
}
