Logoff after idletime in UI5 applications - No SSO in place

Hi

This is further to my question in the link below.

https://answers.sap.com/questions/269149/sap-fiori-launchpad-auto-logoff-after-inactivity.html

So as i understand to use standard ABAP session management for time out using http/security_session_timeout we need to set the parameter login/create_sso2_ticket=3.

But our ECC is connected to other systems which needs logon tickets /SAML2 etc meaning the login/create_sso2_ticket has to be 2. So we cannot roll back the value to 3.

Can you please advise if there is any other way to achieve the logoff functionality either through code in the UI5 application or else ?
