Trash order send email wooocommerce - email

Question

Hello what is the hook to send an email when the order is moved to the trash?
I have this code that works when the order is canceled or fails but I also need to send an email when the order is moved to the trash.
add_action('woocommerce_order_status_changed', 'send_custom_email_notifications', 10, 4 );
function send_custom_email_notifications( $order_id, $old_status, $new_status, $order ){
if ( $new_status == 'cancelled' || $new_status == 'failed' ){
$wc_emails = WC()->mailer()->get_emails(); // Get all WC_emails objects instances
$customer_email = $order->get_billing_email(); // The customer email
}
if ( $new_status == 'cancelled' ) {
// change the recipient of this instance
$wc_emails['WC_Email_Cancelled_Order']->recipient = $customer_email;
// Sending the email from this instance
$wc_emails['WC_Email_Cancelled_Order']->trigger( $order_id );
}
elseif ( $new_status == 'failed' ) {
// change the recipient of this instance
$wc_emails['WC_Email_Failed_Order']->recipient = $customer_email;
// Sending the email from this instance
$wc_emails['WC_Email_Failed_Order']->trigger( $order_id );
}
}

Try this:
add_action('woocommerce_order_status_changed', 'send_custom_email_notifications', 10, 4 );
function send_custom_email_notifications( $order_id, $old_status, $new_status, $order ){
if ( $new_status == 'cancelled' || $new_status == 'failed' || 'trash' == get_post_meta($order_id, 'post_status', true) ){ //added extra condition here
$wc_emails = WC()->mailer()->get_emails(); // Get all WC_emails objects instances
$customer_email = $order->get_billing_email(); // The customer email
}
if ( $new_status == 'cancelled' ) {
// change the recipient of this instance
$wc_emails['WC_Email_Cancelled_Order']->recipient = $customer_email;
// Sending the email from this instance
$wc_emails['WC_Email_Cancelled_Order']->trigger( $order_id );
}
elseif ( $new_status == 'failed' ) {
// change the recipient of this instance
$wc_emails['WC_Email_Failed_Order']->recipient = $customer_email;
// Sending the email from this instance
$wc_emails['WC_Email_Failed_Order']->trigger( $order_id );
}
elseif ( 'trash' == get_post_meta($order_id, 'post_status', true) ) {
// change the recipient of this instance
$wc_emails['WC_Email_Failed_Order']->recipient = $customer_email;
// Sending the email from this instance
$wc_emails['WC_Email_Failed_Order']->trigger( $order_id ); //trigger some email here
}
}
