I am trying to inject my custom product tab in storefront on product view page, but it's not displaying. For this I am written below code.

**registration.php**

    <?php
    \Magento\Framework\Component\ComponentRegistrar::register(
        \Magento\Framework\Component\ComponentRegistrar::MODULE,
        'Test_ProductTabs',
        __DIR__
    );

**Test/ProductTabs/Block/CustomTab.php**

    <?php
    namespace Test\ProductTabs\Block;
    
    use Magento\Catalog\Model\Product;
    
    class CustomTab extends \Magento\Framework\View\Element\Template{
    
        /**
         * @var Product
         */
        protected $_product = null;
    
        /**
         * Core registry
         *
         * @var \Magento\Framework\Registry
         */
        protected $_coreRegistry = null;
    
        /**
         * @param \Magento\Framework\View\Element\Template\Context $context
         * @param \Magento\Framework\Registry $registry
         * @param array $data
         */
        public function __construct(
            \Magento\Framework\View\Element\Template\Context $context,
            \Magento\Framework\Registry $registry,
            array $data = []
        ) {
            $this->_coreRegistry = $registry;
            parent::__construct($context, $data);
        }
    
        /**
         * @return Product
         */
        public function getProduct()
        {
            if (!$this->_product) {
                $this->_product = $this->_coreRegistry->registry('product');
            }
            return $this->_product;
        }
    
    }

                <module name="Magento_Catalog"/>
            </sequence>
        </module>
    </config>

                   <arguments>
                       <argument name="title" translate="true" xsi:type="string">Kit Components</argument>
                   </arguments>
               </block>
