Jplay with Rose (RS 130)

Does anyone have experience with the Jplay app and a Rose streamer.
I use the Rose RS 130.
With JPlay I can play music from Qobuz.
But the Jplay app cannot find the music on the internal SSD.
Rose should be UPnP capable. Has anyone managed to play the music data from the internal SSD via Jplay and what were the settings?
