I am building an app where I would like to send a picture to another authenticated user that is only visible to the user that receives it (if the sender can see it that is fine). The `protected` level looks promising but as far as I understand allows for anyone that is authenticated to see the uploaded content. I was wondering if this is even possible using amplify or if I am misunderstanding something.
