No status icon for client app under fedora 30

I just installed the nextcloud desktop client via the official fedora repository using “dnf install nextcloud-client-2.5.2-2.fc30.x86_64”.
Unfortunately there is no sync indicator status icon appearing in my top panel in gnome.
As already stated I’m using fedora 30 (and my nextcloud server is running on 16.01).
I’ve already tried to find some proper gnome extension but no luck so far. There must be a better way, I guess.

How can I make the systray status icon appear?

Thanks in advance.
