Spotify doesn't show up


I have a Cubox 4Pro. So the latest image available is 2-532 date: 1/18/2019. I install this one. Everything works fine.

Last step, I want to install the Spotify plug in (from Volumio Team). Instaling okay, credentials accepted and Authorized by question. So far so good, but the Spotify is not showing up in the main screen. On Youtube I have seen exactly the same procedure and yes the Spotify is presented in the main screen.

On internet I see a topic: ‘How to get the Spotify plugin working’. There, I see a procedure to invoke entries via SSH, before installing the Spotify plug in. So Im puzzled.

Can somebody explain to me what is the right procedure. I can imagine that SSH is not necessary. The plug in is doing the job?
