Gnome extensions like System Monitor in Alpine linux can't see gliptop

System Monitor or Tophat gnome extensions don't work in fresh installation of Alpine linux. I can see error: > Requiring GTop, version none: Typelib file for namespace 'GTop' (any > version) not found I have installed these two: apk add libgtop gcompat so I think that library is in the OS, however gnome shell extension can't see it. Any idea how to proceed with debug, how can I see what's wrong?
