How to Download file from PHP using call API? - reactjs

Question

I need download a file from a directory in Symfony. The problem is, I need download this file when I am authenticated.
For that, I create a endpoint (GET method) with an ID (the id file), and I am doing the call from a React app passing in the Headers an authorization bearer.
The problem is, the file is not download directly, but if I enter in DevTools from Chrome, I see that in the response exists the file, but it is not downloaded.
This is the PHP code:
$file = new File($fullPath);
return $this->file($file);
How could I download the file?

This is an example code of mine:
/**
* #param Product $product
* #param TranslatorInterface $translator
*
* #SWG\Response(
* response=200,
* description="Get allergensheet of a product",
* )
* #SWG\Tag(name="Product")
*
* #Route("/allergensheet/{id}", methods="GET")
*
* #Security(name="Bearer")
* #return Mixed
*/
public function downloadAllergenSheet(Product $product, TranslatorInterface $translator) {
$allergens = $product->getAllergens();
if($allergens instanceof Allergens) {
if($allergens->getHasSheet()) {
$fs = new Filesystem();
if($fs->exists($translator->trans($product->getArticleNr() . '_allergensheet'))) {
return new BinaryFileResponse($translator->trans($product->getArticleNr() . '_allergensheet'));
}
else {
return new JsonResponse(false, Response::HTTP_NO_CONTENT);
}
}
else {
return new JsonResponse(false, Response::HTTP_NO_CONTENT);
}
}
else {
return new JsonResponse(false, Response::HTTP_NO_CONTENT);
}
}
maybe this can help?
This if for downloading a PDF file which contains some information about a product.
