I'm using RedBean PHP and doing registration, but I'm having trouble adding ReCaptcha. Please help me add it.

<?php 
require "db.php";

$data = $_POST;
if (isset($data['do_signup']) ) 
{

//регистрация

  $errors = array();
  if( trim($data['login']) == '' ) 
  {
    $errors[] = 'Введите логин';
  }


  if( trim($data['email']) == '') 
  {
    $errors[] = 'Введите email';
  }

  if( $data['password'] == '') 
  {
    $errors[] = 'Введите пароль';
  }

  if( $data['password_2'] != $data['password']) 
  {
    $errors[] = 'Пароли не совпадают';
  }

  if(R::count('users', "login = ?", array($data['login'])) > 0 ) 
  {
    $errors[] = 'Пользователь с таким логином уже существует';
  }

  if(R::count('users', "email = ?", array($data['email'])) > 0 ) 
  {
    $errors[] = 'Пользователь с таким email уже существует';
  }


  if ( empty($errors) ) 
  {
      //успешно
    $user = R::dispense('users');
    $user->login = $data['login'];
    $user->email = $data['email'];
    $user->password = password_hash($data['password'], PASSWORD_DEFAULT);
    R::store($user);
    echo '<div class="alert alert-success" role="alert">Вы успешно зарегистрированы!</div>';

  } 
   else 
  {
    echo '<div class="alert alert-danger" role="alert">'.array_shift($errors).'</div>';
  }
}
?>

$response = $_POST["g-recaptcha-response"];
      if (empty($response)) {
        //false;
      }
      $url = 'https://www.google.com/recaptcha/api/siteverify';
      $data = array(
        'secret' => '',
        'response' => $response
      );

      $options = [
        'http' => [
        'method' => 'POST',
        'content' => http_build_query($data)
        ]
      ];

      $context  = stream_context_create($options);
      $verify = file_get_contents($url, false, $context);
      $captcha_success = json_decode($verify, true);
        if (!$captcha_success->success) {
          //false
        }

In principle, here is a good article on connecting Google reCAPTCHA v3: https://blog.lisogorsky.ru/google-recaptcha-v3
