How do I enable a power up script on my player from another gameobject?

Im doing a 2D platformer game and it has power ups but not like jump boost or speed boost the power ups are like in super mario bros 3 like if you pick it up you can perform melee attacks or another one that allows you to shoot projectiles and I already created the scrips of the specific power ups and I put them into the player and they are disable by default and the player starts without them so now i want that when it picks up a power up it enables the scrip and allows perform the actions of the power up. This is the code I set to the power up for the player to pick it up` { private void OnTriggerEnter2D(Collider2D collision) { if(collision.tag == "Player") { GameObject player = player.GetComponent(enable = true);

     }
   
    
 }`
