How to unpublish CB language plugins

[object Object] I need to unpublish a bunch of language plugins that got installed in bulk and are not needed.
It seems obvious to follow this:
From Community Builder: Plugin Management I select the language I don't need and click Unpublish.
This generates an error "Cannot unpublish row id XXX because: Language plugins cannot be unpublished!"

What is the proper way to unpublish those?

Thanks.

Language plugins can't be unpublished. Simply delete them if you don't need them.

Thank you for reply.
Are you talking about deleting files/folders from website instead of Joomla backend?
If yes, where are those languages located and how do I identify which folder or file I should delete?
If not, where do I go in backend as admin to delete those?

No, you should see the language plugins within CB > Plugin Management. Simply select them via their checkboxes and click the "Delete" button on the toolbar at the top of the page. You should not have to do any kind of manual file management in CB.

Thanks, it works.
Just a thought, would it be hard to stick this little instruction on the error message from uninstall attempt?

Error message from uninstall attempt of what? Do you mean the attempt to unpublish them? We're certainly open to improving UX whenever possible. If you can provide some instructions on what you were trying to do we can look into it further.
