     * Hooks in Gateways
     * It’s important to note that adding hooks inside gateway classes may not trigger.
     * Gateways are only loaded when needed, such as during checkout and on the settings page in admin.
     * You should keep hooks outside of the class or use WC-API if you need to hook into WordPress events from your class.
