With CAM-12210, we introduced a quick fix for Notifications not shown. Notifications on route changes are not displayed.

• Create a React Service for Notification Dispatching similar to https://github.com/camunda/camunda-bpm-webapp/blob/4bc7a90c1a621d940bacdf3ff26f6dfb9328c458/ui/cockpit/src/legacy/camunda-commons-ui/lib/util/notifications.js
• Use angularModuleSetup to map the angular `Notifications` service to the react/vanilla one.
• Create a Global Notifications Panel in the React app
  If we keep the same interface, Notifications generated in angular can be displayed in React as well, as display and dispatching are separate.

• Notifications shown when switching routes are displayed, e.g. a message after logout
