Wait in unity(coroutine not working)

Hi, I am trying to make game wait for a number of seconds when the player gets a powerup. I have this drink object so when the player collides with this drink, the user gets a power-up. I want the game to wait for 5 seconds before the powerup is gone. I tried using Coroutines but they don't work for me. here is some of my code:

inside my OnTriggerEnter: if (coll.collider.tag == "powerUpDrink") { activePowerup = true; DestroyObject(coll.gameObject); GetComponent().color = Color.red; rage_text.SetActive(true);

         //Wait for 5 seconds
         StartCoroutine(wait(5f));
      
         rage_text.SetActive(false);
         GetComponent<Image>().color = Color.green;
         DestroyObject(coll.gameObject);
         activePowerup = false;
     }

this is outside of OnTriggerEnter(): IEnumerator wait(float sec){ yield return new WaitForSeconds(sec); }

thanks in advance :)
