[keycloak-user] sso timeouts ??

[java_os]

I am using Standard Flow Enabled with javascript adapter connecting to
rest bearer-only apis.
SSO Session idle set 2h. User is using the app, it redirects to login page
before 2h is reached.
Anyone here knows what is the right realm setting if I want to have a user
working on a sso session for a number of hours?
I guess not fully understand the Token lifespan vs SSO session timeout and
which one rules, etc.
