Bookmark Manager Tools Request

Hello, I have got my Brave Sync up and running across 5 different devices and that is great!

However this has resulted in many duplicate folders and individual links.

It would be nice to have more tools to deal with this in the Bookmark Manager (delete duplicates, group by url, sort by, etc), I really do not want to spend hours going through everything one by one myself.

Failing that, can you recommend a third-party solution?
