8.3 File Upload route permissions issue

The CSRF token for your current session can be retrieved from /data/app/session.

I banged my head on this. Wrong approach, apparently. My IDE is happy with this:

const csrf = useSelector((store: ReduxRootState) => store.userSession.csrfToken);

Will test tomorrow. My brain is fried for the day.
