Как нажать на UI кнопку с использованием raycast?

Управление персонажем от первого лица, тут ничего необычного:

using UnityEngine;
 
public class PCPlayerController : MonoBehaviour
{
    private float playerSpeed = 5f;
    private float jumpPower = 200f;
    private bool onGround;
    [SerializeField]private Rigidbody playerRigidbody;
    private void Update()
    {
        GetInput();
    }
 
    private void GetInput()
    {
        if (Input.GetKey(KeyCode.W))
        {
            transform.localPosition += transform.forward * playerSpeed * Time.deltaTime;
        }
 
        if (Input.GetKey(KeyCode.S))
        {
            transform.localPosition += -transform.forward * playerSpeed * Time.deltaTime;
        }
 
        if (Input.GetKey(KeyCode.D))
        {
            transform.localPosition += transform.right * playerSpeed * Time.deltaTime;
        }
 
        if (Input.GetKey(KeyCode.A))
        {
            transform.localPosition += -transform.right * playerSpeed * Time.deltaTime;
        }
 
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (onGround == true)
            {
                playerRigidbody.AddForce(transform.up * jumpPower);
            }
        }
    }
    private void OnCollisionEnter(Collision collision) 
    {
        if (collision.gameObject.tag == "Ground")
        {
            onGround = true;
        }
    }
 
    private void OnCollisionExit(Collision collision) 
    {
        if (collision.gameObject.tag == "Ground")
        {
            onGround = false;
        }
    }
}
 
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class PCPlayerCameraController : MonoBehaviour
{
    private float mouseX, mouseY, xRotation;
    [SerializeField]private Transform Player;
    [SerializeField]private float mouseSensitivity = 400f;
    private void Start() 
    {
        Cursor.lockState = CursorLockMode.Locked;
    }
    private void Update()
    {
        mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
        mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
 
        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90, 90);
        transform.localRotation = Quaternion.Euler(xRotation, 0, 0);
        Player.Rotate(mouseX * Vector3.up);
    }
}

По плану, в разные моменты должен появляться UI типа такого(обычные кнопки):

как на них можно нажать?
