How to Keep a UI Button stay highlighted (or at least showing highlighted color) after clicking somewhere else?

Question

I know this question has been asked many times, but the answers are mostly using toggles.

In my case, I have to use "Button". It has to be button.

Is there any way to keep the button highlighted (or at least showing a highlighted color) after I click elsewhere except for the button itself. And it only change back to normal unless I click on another button.

Yes, it looks like 99% the same as a tab menu. But I have to achieve this using "button element".

I hope someone could help me with this. Thanks!!

p.s. btw, I found similar question but I couldn't get his solution to work: http://answers.unity3d.com/questions/1155697/how-to-keep-your-button-selected-after-clicking-aw.html

It's an old question but in case someone is looking for the answer, I wrote this simple script to keep the last selected game object selected at all times. Just add this to your EventSystem object.

 using UnityEngine;
 using UnityEngine.EventSystems;
 
 public class EventSystemKeepSelected : MonoBehaviour
 {
     private EventSystem eventSystem;
     private GameObject lastSelected = null;
     void Start()
     {
         eventSystem = GetComponent<EventSystem>();
     }
 
     void Update()
     {
         if (eventSystem != null)
         {
             if (eventSystem.currentSelectedGameObject != null)
             {
                 lastSelected = eventSystem.currentSelectedGameObject;
             }
             else
             {
                 eventSystem.SetSelectedGameObject(lastSelected);
             }
         }
     }
 }
