OnTriggerEnter not working (750089)

Ok… so I’m making a script so that you can pick up grenades, but the code isn’t working for some reason… I followed a tutorial by Brackeys because, in his powerups video, he uses that method to make the object disappear, just like I want my grenade to. the collider is set to trigger, my player is marked with the tag “player”, and the pickup script is on the grenade, but it’s still not working. Any advice?

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

public class GrenadePickup : MonoBehaviour
{
    void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            Pickup();
        }
    }

    void Pickup()
    {
        Destroy(gameObject);
    }
}

Check out when the collision will produce message. You need something on the player as well. Like kinematic rigidbody or something.
