How to make a restart button pop up after character has died?

Question

So I'm kind of new to this Canvas UI button and was wondering how to make a Restart button pop up after the character has died.

I already have a onclick script that restarts the level if it is pushed, but I don't know how to make the button not show up until the character has died.

Would it be somewhere along the lines of:

 (Button is invisible)
 
     if(dead)
     {
          //Make Button visible
     }

you could use SetActive and assign the button in the editor like this

      public gameObject RestartButton
         
         if(dead)
              {
                   RestartButton.SetActive(true);
              }
 else
 {
  RestartButton.SetActive(false);
 }

this should make the gameobject button visisble aslong as the object is dead and not visisble aslong as the object is alive

Something like this will make the button invisible and disabled by setting the alpha value of the text and the button sprite to 0 - fully transparent, and by disabling the Button component to make it unclickable.

 #pragma strict
 import UnityEngine.UI;
 
 var restartButton : Button;
 var restartText : Text;
 var dead : boolean = false;
 
 function Start ()
 {
     restartButton.GetComponent(Image).color.a = 0.0;
     restartText.GetComponent(Text).color.a = 0.0;
     restartButton.GetComponent(Button).enabled = false;
 }
 
 function Update ()
 {
     if(dead == true)
     {
         restartButton.GetComponent(Button).enabled = true;
         restartButton.GetComponent(Image).color.a = 1;
         restartText.GetComponent(Text).color.a = 1;
 
     }
 
     else
     {
         restartButton.GetComponent(Button).enabled = false;
         restartButton.GetComponent(Image).color.a = 0;
         restartText.GetComponent(Text).color.a = 0;
     }
 }

hope it helps. although this might not be most convenient way, it's the only way I know.
