How to delete a file saved on levels

I saved a preset file "remove-cast-color" on levels. Pls refers to screenshot.  How can I delete it on screen ?

I can only delete this file on Terminal of Ubuntu 20.04 running;

Code:

$ rm /home/satimis/.config/GIMP/2.10/levels/remove-cast-yellow

To remove colour casts;
Apply Colors > Auto > White Balance from the main menu. This should automatically remove colour casts from most photos but not 100% workable.

On Internet I found following document;

That document is for GIMP 2.8.  I'm running GIMP 2.10 here.  The screen is different.  Pls help.  Where can I find relevant document fro GIMP 2.10?

Thanks
