..in the sub-menu "Power / Session" of the Application Menu?

How does this work with KDE Plasma 5.20.5 / 2022 ?
(These items (Lock, Log Out, Switch User, Sleep, Restart, Shutdown) are not present in the KDE menu editor !!??)

Especially:

- How can menu items and icons be changed / removed / added in this "Power / Session" sub-menu?
- How to change the commands (e.g. use shutdown command with own parameters)?
- Where are the config files (and paths in filesystem) for these applications?

Thanks in advance!
K.

Anybody knows this?
