Bookings: add return date to order email

By default, Woocommerce Bookings only shows the starting date in the booking overview. I added the return date using this code:

add_filter( 'woocommerce_get_item_data', 'so_34900999_display_cart_data', 10, 2 );
function so_34900999_display_cart_data( $item_data, $cart_item ){

    if ( ! empty( $cart_item['booking'] ) ) {
        $date_format = apply_filters( 'woocommerce_bookings_date_format', wc_date_format() );
        $time_format = apply_filters( 'woocommerce_bookings_time_format', ', ' . wc_time_format() );
        $end_date = apply_filters( 'woocommerce_bookings_get_end_date_with_time', date_i18n( $date_format, $cart_item['booking']['_end_date'] ) );

	$item_data[] = array(
            'key'    => __( 'End Rental Period', 'your-textdomain' ),
            'value'   => $cart_item['booking']['_end_date'],
            'display' => $end_date,
        );
    }
    return $item_data;
}

When the booking/payment is completed, a processing email is sent. Again, only the starting date is mentioned but for legal purposes I need to add the return date as well. How do I do this? I think I need to add a filter in functions.php but I’m not sure.

EDIT: I notice that the booking end date is included when I manually add a booking (without order). So I guess it is not that difficult to implement?

Many thanks in advance.
