How to preview a box file using a Preview token and a fileID?

[wangqiwei66]

Previously I can get a manage token to pass the box authentication . But now I can only get a preview token (as. downscope token) ,which reponse 403 .
So would you pls tell me : I got a## preview token and the associated ## fileID ,can I use that to preview a box file ? If yes ,how ? thanks a lot .

I haven't attempted it, but I believe that it would be possible to create a custom BOXAbstractSession object, with the given accessToken, and from that create a BOXContentClient and BOXPreviewClient. This does indeed seem like a missing feature.
