Connecting VLC iOS App to Plex on Mycloud home 6TB

Just purchased a my cloud 6TB for the house. Have a Plex server running on it but the playback in the Plex app is clunky and over complicated. Can I use the VLC app in iOS to access Plex on the NAS directly? I know I can hit ‘open in VLC’ from the my cloud app but want to view my NAS from the VLC app directly. Screenshot from the VLC app Network options - this is as far as I get but it wont access the drive. Thanks

VLC iOS App version 3.2.13
