1. User with the role reader should have the ability to send maintenance to the review.
   • Solution: based on the jwt groups, change title from Submit to "Submit to review" or similar.
2. User with the role editor should have the ability to approve the maintenance and publish it.
   • You can get the list of maintenances in the status 'pendint_review' via endpoint v2/events?type=maintenance&status=pending_review
   • That's the pendint_review, approved are private statuses, you can get them only then you are authrorised.
   • How the user approve the maintenance. User should open the event details and if the user has rights (has group 'sd_operators' or 'sd_admins') the event page should have the button approve. The button approve will just change the event status and send PATCH request to the backend.
3. We should have a notification (popup or toaster or something else) for editors if there are events in the status "pending review"
4. The maintenance should have a field for the contact email like DL-TSI_OTC_Storage_Squad@t-systems.com (mailto:DL-TSI_OTC_Storage_Squad@t-systems.com)
