'END' button on IC Web Client?

Hi all,

We are working on SAP CRM Interaction Center webclient 4.0.

On top of the page we see a Toolbar with several buttons. One of the buttons is end. (Used to kill the existing session)

Can anyone guide me where exactly is the code for this 'End' event?? Which view, controller etc.?

Full rewards guranteed for helpful answers 😊
