Panel isn't opening after hitting the tab key, and its not even saying I pressed the key?

When I run my program, it doesnt even say "Key pressed" in my debug line, on top of that, the panel is not opening after hitting "tab".

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class TabPanel : MonoBehaviour
 {
     public TabPanel tabPanel;
 
 
     private void Start()
     {
 
     }
 
 
     private void Update()
     {
         if (Input.GetKeyDown(KeyCode.Tab))
         {
             tabPanel.gameObject.SetActive((tabPanel.gameObject.activeSelf));  //need to add this line to make the toggling work
 
             Debug.Log("Key pressed");
         }
     }
 }
