WooCommerce: Get chosen shipping method for package and store it as order item meta data

Question

Case:

In checkout packages are splited by shipping class of products (different brands). Every package have own shipping method that customer can choose.

And finally when customer make an order I need to store chosen shipping method for every product in meta_data so I can see it in order details on admin panel and for the RESTAPI (I use some external services to manage orders).

I tried something like this but I know this is mess, I don't understand how to handle session data and store it in order data.

  add_action( 'woocommerce_checkout_create_order_shipping_item', 'order_shipping_item', 20, 4 );
  function order_shipping_item($cartItemData,$order){

    foreach ( WC()->cart->get_shipping_packages() as $package_id => $package ) {
        // Check if a shipping for the current package exist
        if ( WC()->session->__isset( 'shipping_for_package_'.$package_id ) ) {
            // Loop through shipping rates for the current package
            foreach ( WC()->session->get( 'shipping_for_package_'.$package_id )['rates'] as $shipping_rate_id => $shipping_rate ) {
                $method_id   = $shipping_rate->get_method_id(); // The shipping method slug
                $instance_id = $shipping_rate->get_instance_id(); // The instance ID
                $label_name  = $shipping_rate->get_label(); // The label name of the method

            }
        }
        foreach ($package['contents'] as $item) {
          $item->add_meta_data('_shipping_method',$label_name);
          # code...
        }
    }
  }

Right now I have no idea how to achieve this, any clues? help!

Here is the way to save as custom order item meta data the chosen shipping method details for each order item:

// Custom function that get the chosen shipping method details for a cart item
function get_cart_item_shipping_method( $cart_item_key ){
    $chosen_shippings = WC()->session->get( 'chosen_shipping_methods' ); // The chosen shipping methods
    
    foreach( WC()->cart->get_shipping_packages() as $id => $package ) {
        $chosen = $chosen_shippings[$id]; // The chosen shipping method
        if( isset($package['contents'][$cart_item_key]) && WC()->session->__isset('shipping_for_package_'.$id) ) {
            return WC()->session->get('shipping_for_package_'.$id)['rates'][$chosen];
        }
    }
}

// Save shipping method details in order line items (product) as custom order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'add_order_line_item_custom_meta', 10, 4 );
function add_order_line_item_custom_meta( $item, $cart_item_key, $values, $order ) {
    // Load shipping rate for this item
    $rate = get_cart_item_shipping_method( $cart_item_key );

    // Set custom order item meta data
    $item->update_meta_data( '_shipping_rate_id', $rate->id ); // the shipping rate ID
    $item->update_meta_data( '_shipping_rate_method_id', $rate->method_id ); // the shipping rate method ID
    $item->update_meta_data( '_shipping_rate_instance_id', (int) $rate->instance_id ); // the shipping rate instance ID
    $item->update_meta_data( '_shipping_rate_label', $rate->label ); // the shipping rate label
    $item->update_meta_data( '_shipping_rate_cost', wc_format_decimal( (float) $rate->cost ) ); // the shipping rate cost
    $item->update_meta_data( '_shipping_rate_tax', wc_format_decimal( (float) array_sum( $rate->taxes ) ) ); // the shipping rate tax
}

Code goes in functions.php file of your active child theme (or active theme). Tested and works.
