提交订单后如何发送额外的电子邮件（Woocommerce）？

Question

I am trying to send an extra email after an order is sent on woocommerce and I think I am using the wrong action/hook. Where am I going wrong?

function email_processing_notification( $order_id ) {

    $order = wc_get_order( $order_id );

    // load the mailer class
    $mailer = WC()->mailer();

    $recipient = '***@gmail.com';
    $subject = __('Some Subject', 'test');
    $content = get_processing_notification_content( $order, $subject, $mailer );
    $headers = "Content-Type: text/html\r\n";

    $mailer->send( $recipient, $subject, $content, $headers );

}

add_action( 'woocommerce_order_status_pending_to_processing_notification', 'email_processing_notification', 10, 1 );


function get_processing_notification_content( $order, $heading = false, $mailer ) {

    $template = 'emails/customer-processing-order.php';

    return wc_get_template_html( $template, array(
        'order'         => $order,
        'email_heading' => $heading,
        'sent_to_admin' => true,
        'plain_text'    => false,
        'email'         => $mailer
    ) );
}
