Set minimum per item + Distance rate

I see the surcharge option, but this does not multiply by number of products

this seems to have done the trick, courtesy of chatgpt:

            // Count total items in the cart
            $total_items = 0;
            foreach ( $package['contents'] as $item_id => $values ) {
                $total_items += $values['quantity'];
            }

            $surcharge = $this->get_rate_field_value( 'surcharge', $rate, '' );

            if ( ! strlen( $surcharge ) ) {
                $surcharge = $this->surcharge;
            }

            if ( $surcharge ) {
                $surcharge_type = $this->get_rate_field_value( 'surcharge_type', $rate, 'inherit' );

                if ( ! $surcharge_type || 'inherit' === $surcharge_type ) {
                    $surcharge_type = $this->surcharge_type;
                }

                if ( ! $surcharge_type ) {
                    $surcharge_type = 'fixed';
                }

                if ( 'fixed' === $surcharge_type ) {
                    $cost += $surcharge * $total_items; // Apply surcharge per product
                } elseif ( 'percent' === $surcharge_type ) {
                    $cost += ( ( $cost * $surcharge ) / 100 );
                }
            }
