Download media resources

[lCassieL]

I receive a message from a client with a file, I recognize its . How can I download this file to a specific directory?
I found only this:
$response = $whatsapp_cloud_api->downloadMedia('');
But I cannot understand what to do next.

I found solution to get the file - $response->body() :
$whatsapp_cloud_api = new WhatsAppCloudApi([
'from_phone_number_id' => WHATSAPP_PHONE_ID,
'access_token' => WHATSAPP_TOKEN,
]);
$response = $whatsapp_cloud_api->downloadMedia($media_id);
file_put_contents('files/image.jpg', $response->body());
