How do i activate lose screen

I have a lose screen that activates after you fail a level all that is fine but how do i match the game object in my hierarchy to the one in the script i tried using tags but i keep getting null reference exception i know what it means but i just can’t get it to work i even tried looking up a guide by unity but all they showed me was gameobject.SetActive(false); they didnt tell me if i needed to put anything outiside of script and I’m really confused please help!

There are two simple ways to get one object into the scene:

The first one is to find the object by code (c#):

GameObject Menu = GameObject.Find("name");

NOTE: This will not find anything if the object is not active

The second one is to declare a public variable and assign its value from editor

public GameObject Menu;

If menu object is disabled then you can use

  Menu.SetActive(true);
