Can't save to onedrive or local file system without virt-viewer.

I'm running winapps over Manjaro per the very helpful install instructions at https://github.com/goddard-guryon/winapps and it works wonderfully well! But ... if I want to save to my linux file system via spice-webdav I can only do that when I start the full desktop via virt-viewer. Otherwise the service doesn't run, and that means I have to close my app session and start a desktop session and then close that and restart the app ...

Oh, also the app session has no Internet access so I can't do the obvious thing and save to onedrive.

So altogether that's annoying and it would be really good to have a fix or workaround, many thanks in advance!
