Open File Picker Dialog

My app wants to export files to users' Box accounts. I want to allow them to easily select a destination folder. I don't want to include the Box UI elements in my node modules. It would be great to launch a Box URL in a popup window with a redirect uri (similar to the oauth flow) that posts the path of the folder selected by the client. This would make it very easy to allow the client to select a destination folder and give my app the info required to upload content to that destination with very minimal code.

No file or test entry point is identified. Start by reviewing the SDK's OAuth flow and the Box URL and redirect URI handling described in the request. Done would mean a supported way for an app to open a Box picker and receive the selected destination folder path without embedding Box UI elements.
