How to make your notifications read?

Question

Toaster

How can I clear the list of all unread notifications? I have already flipped through the first 10 pages, I still have 120 more unread.
And how do I know that I received a response? on the left, the list of events is completely non-informative.

Answer 1

To the right of the heading "Notifications" is an ellipsis, there is a menu item "Mark all read"
