Box File Picker in filtered view?

I'm new to the file picker and I am trying to do something that may or may not be possible.

In a desktop app one can open a file open dialog and put it in a filtered view (say *.pdf). Well, for my task in box I am looking to see if maybe I can open up the filepicker in a filtered mode for say folders that can be shared.

I am using the docs located here : https://docs.box.com/v2.0/docs/the-box-file-picker

But I don't see a filtered view as an option.  But perhaps I need to clean my glasses 🙂

Does anyone know if this is possible?
