Looks good overall! Left a few small comments. Also, I did notice that the live bell is only working for admins/moderators and it's not working for regular commenters. This seems to be due to the @auth placed on the notificationCount.

I looked into it and have fixed this issue. The check is now handled gracefully in the resolver and no longer needs an @auth(...) directive since the conditions are simple. Should work properly now for all users!
