unity3d - Why doesn't my function appear in the On Click field in Unity?

Question

I wrote a simple script for the button and threw it in the" On Click " in the button, but my Button1 function is not displayed there. How to solve this problem?

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

public class Nikita : MonoBehaviour
{
public void Button1()
{
    Debug.Log("button clicked");
}

// Start is called before the first frame update
void Start()
{
    Debug.Log("started");
}

// Update is called once per frame
void Update()
{
    
}  
}

Answer 1

you want to set the button by: public Button ButtonName;

then in start you want to add listener: ButtonName.onClick.AddListener(ButtonFunction);

then add button function :void ButtonFunction() {

          Debug.Log("string here")
    }

then you just drag the button to the inspector, set the onclick in inspector and the option would be under the name Nikita-ButtonName
