Magento2 - Getting Grouped and Configurable Product ID from Simple Product Id

Question

I am trying to get a Grouped product ID (and then the grouped product URL, but I can do this) from a Simple product which is part of this grouped product.

I tried the following:

$parents = $product->getTypeInstance()->getParentIdsByChild($productId);

Without success. Thanks!

You can get this way:

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\GroupedProduct\Model\Product\Type\Grouped $groupedProduct,
        array $data = []
    ) {
        $this->groupedProduct = $groupedProduct;
        parent::__construct($context, $data);
    }
    /**
      * $childId Child Item id
      */
    public function getGroupedProductId($childId) {
     return $this->groupedProduct->getParentIdsByChild($childId);
    }
