Bought Oculus 3s with Gorilla Tag Cardboard Monkenaut Bundle, but cant find bundle

I just bought a new Oculus 3S for my son from Amazon during Prime days, and it is supposed to come with a Gorilla Tag Cardboard Monkenaut Bundle. I set up the Oculus, installed the game, but can't find the items that come with the bundle and the extra shiny rocks haven't been added to my account. My son played this game a ton on the Oculus 2, so he knows where to go to look for things, and he can't find any of these items in the game. I havent gotten any notification or email saying these items were added to my account. Does anyone know how I am supposed to activate this bundle?
