I couldn't find out how to push an xbox game install to the console with Google searches. Here's what I learned on my own.
- Go to xbox store.
- From profile picture choose 'My Microsoft Account'
- Click Order History
- Click on appropriate order
- The bold text below the order number is actually a link. It's evidently a secret
- Click on the link (Resident Evil ...)
- You'll the item description in the store. There's a button to push install.
