I need help in adding an Mpesa (mobile Money) payment gateway.

The code looks something like this

<?php
// In order to prevent direct access to the plugin
defined('ABSPATH') or die("No access please!");

// Event Espresso Payment Gateway header
/* Plugin Name: Event Espresso M-PESA Payment Gateway
* Plugin URI: https://paymentprocessor-script.com/
* Description: M-PESA Payment Gateway for Event Espresso.
* Version: 1.0.0
* Author: Your Name
* Author URI: Your Plugin Website
* Licence: GPL2
*/

// Add action to initialize the payment gateway
add_action('plugins_loaded', 'event_espresso_mpesa_payment_gateway_init');

// Define and enqueue CSS and JavaScript files
function event_espresso_mpesa_adds_to_the_head() {
    wp_enqueue_script('Callbacks', plugin_dir_url(__FILE__) . 'trxcheck.js', array('jquery'));
    wp_enqueue_style('Responses', plugin_dir_url(__FILE__) . '/display.css', false, '1.1', 'all');
}

add_action('wp_enqueue_scripts', 'event_espresso_mpesa_adds_to_the_head');
