Missing indicator new notifications

I keep opening the notification page myself every hour of something, but it would be nice to have some indication if there are new notifications. I believe the Messages Left-Bar-Button does have one.

There is an isUnread property, however the ngClass seems not set when there are unread notifications?

**left-bar.component.html:**

**left-bar-button.component.html:**
[ngClass]="{
'left-bar__dot-unread': isUnread,
'left-bar__dot-inactive': !rla.isActive,
'left-bar__dot-active': rla.isActive
}"

Note: for Messages there seems to be a different css class: notification?
