User Story

As a:

Student/ Teacher

I want:

to be informed about new Chat messages. (something like "You have new messages in Course .../ Unit...")

so that:

I can answer quickly.

Acceptance criteria:

• [ ] A new notification appears if there are new Chat Messages in a course chat
• [ ] A new notification appears if there are new Chat Messages in a unit chat
• [ ] Ensure to get only one notification per Course-Chat
• [ ] Ensure to get only one notification per Unit-Chat

Additional info:

As we already discussed in the meeting it is not necessary to track which message a user has read, but only if there is an updated chat.
