@Klasmic You can not set this function on button press. because function hold multiple parameter. if you have more then 1 parameter in button press function then you can use like this.

 using UnityEngine;
  using UnityEngine.UI;
  using System.Collections;
  
  public class TwoArgs : MonoBehaviour
  {
      //your button
      public Button b;
  
      //control the value to pass to event as you need
      public int x, y;
  
      void Start()
      {
          //register new event to onclick with the variables that control your args
          b.onClick.AddListener(() => CustomClick(x, y));
      }
  
      public void CustomClick(int a, int b)
      {
          //do something you want
          print(a + b);
      }
  }
