"Browsing data" meaning when uninstalling Brave browser

Well thats (very) bad news for me, it seems I’ve maybe lost 6 months of hard work on collecting information.
Why “bookmarks” are not clearly stated in that notification? I was tired that night (two days ago) and I payed attention on word “browsing” so I clicked delete button totally unconscious that I’ll lost whole 6 moths work as my last backup was in April 2019.

Please let me know if there is, by any chance, some solution to recover this great lose?

I find this: Still can't recover my bookmarks
