netlifyIdentity force logoff

I am using the netlifyIdentity widget to authenticate users on the site. I want to logoff users that have been inactive for a length of time. Can I use the widget to do that? Is this feature documented?

e.g.

if (!logged_out && last_active > 0 && new Date() - last_active > CUTOFF_TIME) {
    logoutUser();
}

It’s documented: netlify/netlify-identity-widget: A zero config, framework free Netlify Identity widget (github.com)
