Where can I find the .desktop files for the "Copy To" and "Move To" service menus for Dolphin file browser

I am using KDE Neon. I want to create modified versions of the "Move To" and "Copy To" services in the Dolphin file browser. I want to find the built-in services, copy their .desktop files, and edit the copies, making a new pair of services with the new option. I ran

-config --path services

and got /home/myusername/.local/share/kservices5/:/usr/share/kservices5/ I checked in both of these locations and could not find .desktop files which appeared to be related to Copy To or Move to. Do Copy To and Move To even have .desktop files associated with them? If so, where would I find them.
