How to know if button was previously pressed

Hi there,
I have a set of buttons in my scene under the same parent GameObject.
In the script attached to the parent Game Object I need to know which of the buttons has been pressed in order to run different functions.

Since the isPressed() method of Buttons is protected and not publicly accessible, how can I understand which button is pressed?

What I am looking for is a function of this type:

private Button findClickedButton()
    {
        var buttonList = GameObject.FindObjectsOfType<Button>();
        foreach (var curButton in buttonList)
        {
            // if(curButton.isPressed())
            //     return curButton;
        }
    }

Thanks for any support!

In the OnClick event you can select the function you want to run when a specific button is pressed.
If you have a button controller script on the parent you can select this script in your buttons and select this function to be executed.

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ButtonController : MonoBehaviour
{
    private Dictionary<int, Button> _clickedButtons = new Dictionary<int, Button>();

    public void ClickFunction(GameObject gameObj)
    {
        var button = gameObj.GetComponent<Button>();
        if (button != null)
        {
            int uniqueId = gameObj.GetInstanceID();
            if (!_clickedButtons.ContainsKey(uniqueId))
            {
                _clickedButtons.Add(uniqueId, button);
            }
        }
    }
}

_clickedButtons.Values will contain all your pressed buttons.
