List of steps to reproduce (step by step, including full links if applicable):

• Click notification and mark it as read/archive in primary language
• Look for notification that was marked as read/archive

What happens?:
Read notifications are not available in the list of notifications, and there isn't a separate list for it either.

What should have happened instead?:
Either there is a space for people to see read messages like two versions ago or we display the new designs where notifications marked as read remain in the notifications list but is just unbolded.
