Manually adding UPnP renderer / KEF LS50 Wireless

[Tahini]

Hi,
VLC connects nicely to Fuppes hosted on my NAS, however it doesnt see the LS50 Wireless available locally as a renderer. All that VLC sees is a Google Home Mini I have in the kitchen. Android apps e.g. Bubble UPnP on my phones are able to detect the KEF speakers correctly and use them as renderer, so not sure what is the issue with VLC.

Is it possible to manually add DLNA / UPnP renderers? Or force a new scan? I dont have any other option except 'No Renderer' or 'Google Home Mini'.
