How to make smooth movement through interactive buttons on android in unity3d?

Question

Unity

I made buttons and hung scripts on them, but when I press the button, the machine only twitches once, how to execute the script while the button is pressed?

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

public class CarControl : MonoBehaviour
{
    public GameObject Car;
    public float speed;
   
    public void Start()
    {
        Car.GetComponent<Rigidbody2D>();
    }

   
    public void MoveRightDown()
    {
        transform.position += new Vector3(speed * Time.deltaTime, 0.0f, 0.0f);
        Debug.Log("нажатие на кнопку вправо");
        
    }
    public void MoveRightUp()
    {      
        Debug.Log("нажатие на кнопку вправо");
    }

    public void MoveLeftUp()
    {
        transform.position -= new Vector3(speed * Time.deltaTime, 0.0f, 0.0f);
        Debug.Log("нажатие на кнопку влево");
    }

I tried to call MoveDownRightDown through the update selected event triger, and then stop, but it seems that I'm doing it wrong

I would do this - when you click on the right button - speed = 100 (for example), on the left - speed = -100 .
When the button is released - speed = 0 .
In Update/FixedUpdate move the car using the speed value.
