Different Idle times for Clients

Hi.

We have two applications that will use the same realm for login, but we would like to have different SSO Session Idle time for each applications.

Example:
Application A - We would like to allow idle time up to 30 minutes
Application B - We would like to allow idle time up to 45 minutes.

However the setting to control the idle time, is set in the Realm settings, and not on the clients settings, which makes it hard for us to solve the scenario above.

Is there anyway to solve the problem for Keycloak - Or perhaps by making a background request from Application B after X amount of idle time?

Thanks
Daniel
