Box Integration with Unity3d for iOS

Hi all,

I'm currently trying to access a folder on my box account with a Unity3d app I am developing. Is it possible to somehow transfer a box folder to a local folder on iOS to access these files? Or is there support with Unity and C# (so far I see the answer is no...https://community.box.com/t5/Platform-and-Development-Forum/Box-Oauth2-in-unity/m-p/28772 )? 

To reiterate my question, what would be the best way to move a box folder into a local on iOS such that various apps can access it? Or is there a way for direct integration with Unity and C#?

Thank you for your time!
