How to add touch buttons in a platform game?

Unity Engine
1

I am developing a 2D video game for android, the only thing I need to finish is to make the touch controls. The video game only contains movement to the right and left and jump (like MarioBros). I have already created the buttons on canvas, I only need the script, I would greatly appreciate your help, I enclose my player code in case you can help me with the modifications.

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


public class PlayerController : MonoBehaviour
{
    public float jumpPower = 15f;
    private bool jump;
    public bool grounded;
    private Rigidbody2D rb2d;
    private Animator anim;
    private GameObject healthbar;
    public GameObject panelGameOver;



    // Start is called before the first frame update
    void Start()
    {
        rb2d = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();

        healthbar = GameObject.Find("Healthbar");
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space) && grounded)
        {
            jump = true;
        }
        anim.SetBool("Grounded", grounded);
    }

    void FixedUpdate()
    {

        {
            if (Input.GetKey(KeyCode.RightArrow))
            {
                if (GetComponent<SpriteRenderer>().flipX == true)
                {
                    GetComponent<SpriteRenderer>().flipX = false;
                }
                GetComponent<Animator>().SetBool("Correr", true);
                transform.Translate(0.1f, 0, 0);
            }
            if (Input.GetKey(KeyCode.LeftArrow))
            {
                if (GetComponent<SpriteRenderer>().flipX == false)
                {
                    GetComponent<SpriteRenderer>().flipX = true;
                }
                GetComponent<Animator>().SetBool("Correr", true);
                transform.Translate(-0.1f, 0, 0);
            }
            if (Input.GetKeyUp(KeyCode.LeftArrow) || Input.GetKeyUp(KeyCode.RightArrow))
            {
                GetComponent<Animator>().SetBool("Correr", false);
            }
            //Saltar
            if (jump)
            {
                rb2d.AddForce(Vector2.up * jumpPower, ForceMode2D.Impulse);
                jump = false;
            }

        }






        //
    }
    public void EnemyJump()
    {
        jump = true;


    }

    public void EnemyJumpB()
    {
        healthbar.SendMessage("TakeDamage", 30);
        jump = true;

    }

}

It is very easy.
In the script you need to make public void
and write what do you want to do.
In the settings of buttons at the bottom you will see" runtime only " and below it will be empty filed drag a prefab that contains script you want to do and on right choose script and void that contains action, for example

public void jump(){
if(grounded)
        {
            jump = true;
        }
}

You can don’t edit your script just add public voids
