How do you see all the past read notifications or replies

Hello,

https://tildes.net/notifications/unread shows only the unread notifications.

If I have marked all comment replies are read, that link will show me an empty page.

So I thought that visiting https://tildes.net/notifications/ should show me all the past replies to my comments, but that's returning 404.

So, is there a place where I can see all the read notifications/replies?
