OptionalhandleLog out with through from the RP.
OptionalpostAn optional URL to redirect to after idp logout has completed; this MUST match a logout URL listed in the Client ID Document of the application that is logged in.
If the application is logged in with a Client ID that is not
a URI dereferencing to a Client ID Document then users will
not be redirected back to the postLogoutUrl after logout.
OptionalstateThe value that should be provided in the state query parameter when redirecting
back to the postLogoutUrl.
Note: This parameter should only be provided when a postLogoutUrl is provided. If this value is provided then you should clear it from the URL when redirected back to the postLogoutUrl.
If a function is provided, the browser will not auto-redirect and will instead trigger that function to redirect. Required in non-browser environments, ignored in the browser.
