Input Manager can't detect a already pressed button

I have a handBreak button on my simulator that starts pressed/on, so I need that the InputManager detect if this button is pressed and modifie a boolean. The problem is that the InputManager can’t detect this already pressed button. I tested with keyboard and joystick. Every time I start or reset the game, with the button pressed, it is not detect, I need to unpressed once to start to be detect. Here is a simple code to test it. Any clues? I’m stucked. TKS

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class TestPressed : MonoBehaviour
{
    // Start is called before the first frame update

    [SerializeField]
    private bool button1Pressed;

    [SerializeField]
    private int countB1;

    private GUIStyle guiStyleR = new GUIStyle();
    
    // Update is called once per frame
    void Update()
    {
        if (Input.GetButton("Fire2")){ // using letter "c" on Input
            button1Pressed = true;
            countB1++;

        }
        else
        {
            button1Pressed = false;
            countB1 = 0;
        }

    
        if (Input.GetKeyDown(KeyCode.R)) {

            SceneManager.LoadScene(0);
                
        }
    }

    private void OnGUI()
    {
        guiStyleR.fontSize = 30;
        guiStyleR.normal.textColor = Color.blue;
        guiStyleR.fontStyle = FontStyle.Bold;

        GUI.Label(new Rect(200,10, 220, 40), "B1: " + button1Pressed + " " + countB1, guiStyleR);
       
    }

 }

As update method get called many times per frame, it might not able to catch click event. You should try from this.
