SSO on bussiness plan

We are on the Business plan and we need users to be logged out after closing the browser, or at least prevent Retool from keeping the session for a long time.

I checked Settings → Authentication → Single sign-on (SSO), but it appears to be Enterprise-only in our workspace.

What is the best way on the Business plan to configure a shorter session timeout or force users to re-authenticate after closing the browser?

Do we have access to any setting similar to “Use short session” without upgrading to Enterprise?

Thanks.
