The monthly newsletter playlist-link only leads to the homepage in the browser

For example, the link in the “Playlists from Roon” section always takes me to the roon-homepage.

Maybe I have to configure a special filetype in my browser to open the roon-app?
Which one?

What’s happening is expected behaviour, I assume.
Roon’s playlists can be seen in Roon Remote, on the home page. Underneath ‘your daily mixes’ and above ‘recent activity’.
