Determine what is the minimal set of entitlements sufficient for the returned Account in the above method.

I don't think we need to make it a minimal set of capabilities here. It is a brand new account that the caller is expected to own, so I don't think we should restrict it. They should be allowed to do anything they want with it in the transaction
