answer call silver button KDE, SOLVED Options

[cam1965]

Hi,
how can I answer a call ( dialer-app ) in KDE using the silver button ?
How can I assign this button to do this ?
In lxqt I can use it .
Thank you all.

SOLVED:
In lxqt I've changed the shortcut saytime assigned to the silver button to ALT +S
In KDE I've enabled xss-lock gemian-lock ( disabled in the past )
In KDE I've changed the action when the lid is closed to do nothing.
