ViewContent meta Pixel is not displaying in PDP Page

We are using below code from this github extension for tracking meta facebook pixel events in our Magento PWA Venia Site.

$product = $this->registry->registry('current_product');
            if ($product && $product->getId()) {
                $customData['value'] = $this->_magentoDataHelper->getValueForProduct($product);
                $customData['content_ids'] = [$product->getId()];
                $customData['content_category'] = $this->_magentoDataHelper->getCategoriesForProduct($product);
                $customData['content_name'] = $product->getName();
                $customData['contents'] = [
                    [
                        'product_id' => $product->getId(),
                        'item_price' => $this->_magentoDataHelper->getValueForProduct($product)
                    ]
                ];
                $customData['content_type'] = ($product->getTypeId() == Configurable::TYPE_CODE) ?
                    'product_group' : 'product';
            }
