About network on PS4 app

[LupusEtFlos]

How do I get this to work? I'm on Linux, I've set up a network share, but where on the app itself would I access it? What button do I press? Adding it to the NETWORK field in the cfg file didn't seem to do anything, even the free samples from FFMPEG aren't there.

I'm new to configuring networks on Linux, SMB on Windows was fairly straightforward, so I beg your pardon in advance.
