How to Remove Unused Prefixes?

I’ve noticed that there are some prefixes in my database that are no longer being used. These prefixes were created for tests, but are now unnecessary clutter.

Could anyone please advise on the best method to remove these unused prefixes from the database? I want to ensure that my database remains clean and organized

Did you happen to find a solution to this? The only option seems to be to use bench access to delete it directly from the database, wasn’t able to find anything in the documentation.

Additionally, we’ve made sure there are no documents using that Naming Series at all, so it should be possible to delete.
