Custom Status triggering Custom Email - php

Question

I have created a custom trigger called "Shipped" which seems to work perfectly in my list of options.
function add_new_order_woocommerce_email( $email_classes ) {
// include our custom email class
require( 'includes/class-wc-shipped-order-email.php' );
// add the email class to the list of email classes that WooCommerce loads
$email_classes['WC_Shipped_Order_Email'] = new WC_Shipped_Order_Email();
return $email_classes;
}
add_filter( 'woocommerce_email_classes', 'add_new_order_woocommerce_email' );
function register_shipped_order_status() {
register_post_status( 'wc-shipped', array(
'label' => 'Shipped',
'public' => true,
'exclude_from_search' => false,
'show_in_admin_all_list' => true,
'show_in_admin_status_list' => true,
'label_count' => _n_noop( 'Shipped <span class="count">(%s)</span>', 'Shipped <span class="count">(%s)</span>' )
) );
}
add_action( 'init', 'register_shipped_order_status' );
function add_new_to_order_statuses( $order_statuses ) {
$new_order_statuses = array();
foreach ( $order_statuses as $key => $status ) {
$new_order_statuses[ $key ] = $status;
if ( 'wc-processing' === $key ) {
$new_order_statuses['wc-shipped'] = 'Shipped';
}
}
return $new_order_statuses;
}
add_filter( 'wc_order_statuses', 'add_new_to_order_statuses' );
I have been having issues trying to get this email to trigger when the status is changed to my custom status provided above. I have searched the internet for multiple examples and possible solutions to my problem but have been unable to find anything that helps.
The email template in the code has been created and is in the correct directory location.
<?php
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

$this->id = 'wc_shipped_order';

$this->title = 'Shipped';
// defines the email for customers only
$this->customer_email = true;
// this is the description in WooCommerce email settings

// these are the default heading and subject lines that can be overridden using the settings

// this sets the recipient to the settings defined below in init_form_fields()
$this->recipient = $this->get_option( 'recipient' );

$this->recipient = get_option( 'admin_email' );

A lot of this coding was sourced via other sources and customised to suit my application, however I have been stuck on this one problem for so long I have no decided to resorting to this amazing website to get some expert opinions on what I could possibly be doing wrong or where I may find a solution. (I prefer to learn myself, but my brain can only take so much before it becomes annoyingly hard to solve haha!)
Any help is greatly appreciated!
