Editing the function library

I have node red V 1.22 on raspberry pi 4 installed. Does anybody know how I can edit the library of the function node? There are only the points "open library" and "save library" available. I cannot delete, rename or edit an entry.

You edit by opening an entry, changing it then saving it back over the top.

There is no delete option currently. You can access the library files directly in ~/.node-red/lib/

Thank you very much for the quick answer. I can change to this folder in the terminal and see the entry. But unfortunately this folder is not to see in the file explorer to delete the entry. Unfortunately I'm not so familiar with Linux.

I found the problem. The folder with the library files is a hidden folder, and hidden folders were blocked in the file explorer.
