how to remove another APM session while Logging out from the actual session

Hi

I do have an EdgeClient session and want to run another portal access while launching firefox to this portal access session (this generates me two session - I know). So far so good. But I want to close the portal session in case of closing the EdgeClient session. Within the Event "ACCESS_SESSION_CLOSE" how can I remove another used access session id?

Any hints kindly appreciated sm
