Magento 2.4.6-p1 – DynamicRows not saving data in table

I added a dynamicRow component into product edit page
dynamicRows ui component

But it is not saving any data in my table, i have looked the payload from the POST request and the fields are not listed there.

DataProvider class structure:

namespace VendorModuleUiDataProviderProductFormModifier;

use MagentoCatalogUiDataProviderProductFormModifierAbstractModifier;
use VendorModuleModelResourceModelBookingDateCollectionFactory as 
BookingDateCollectionFactory;
use MagentoCatalogApiDataProductInterfaceFactory;
use VendorModuleModelDataBookingDate as BookingDateData;
use MagentoCatalogModelLocatorLocatorInterface;

class BookingDates extends AbstractModifier
{
  protected $locator;
  protected $bookingDateCollectionFactory;

public function __construct(
    LocatorInterface $locator,
    BookingDateCollectionFactory $bookingDateCollectionFactory
) {
    $this->locator = $locator;
    $this->bookingDateCollectionFactory = $bookingDateCollectionFactory;
}

public function modifyData(array $data)
{
    $product = $this->locator->getProduct();
    $productId = $product->getId();

    if ($productId) {
        $collection = $this->bookingDateCollectionFactory->create()
            ->addFieldToFilter('product_id', $productId);

        $dates = [];
        foreach ($collection as $item) {
            $dates[] = [
                'date_from' => $item->getDateFrom(),
                'date_to' => $item->getDateTo(),
                'slots' => $item->getSlots(),
            ];
        }

        $data[$productId]['product']['extension_attributes']['package_booking_dates'] = $dates;
    }

    return $data;
}

{
    $customFieldset = [

    return $meta;

My custom table schema

<table name="vendor_package_booking_date" resource="default" engine="innodb" comment="Datas e Vagas de Pacotes">
        <column name="entity_id" xsi:type="int" unsigned="true" nullable="false" identity="true" comment="ID"/>
        <column name="product_id" xsi:type="int" unsigned="true" nullable="false" comment="Product ID"/>
        <column name="date_from" xsi:type="date" nullable="false" comment="Data Inicial"/>
        <column name="date_to" xsi:type="date" nullable="false" comment="Data Final"/>
        <column name="slots" xsi:type="int" nullable="false" default="0" comment="Vagas Disponíveis"/>
        <constraint xsi:type="primary" referenceId="PRIMARY">
            <column name="entity_id"/>
        </constraint>
        <constraint xsi:type="foreign" referenceId="VENDOR_BOOKING_PRODUCT_ID_CATALOG_PRODUCT_ENTITY_ENTITY_ID"
                    table="vendor_package_booking_date" column="product_id"
                    referenceTable="catalog_product_entity" referenceColumn="entity_id"
                    onDelete="CASCADE"/>
        <index referenceId="VENDOR_BOOKING_PRODUCT_ID" indexType="btree">
            <column name="product_id"/>
        </index>
    </table>

Can anybody tell me if I miss anything or any correction needed to make it work?
