I think it'd be nice to redirect the user to the login page when you get any user:auth_token_expired error.
For now, I can continue to navigate (until I refresh the page) in the admin panel but it'll not show any data.

Also it doesn't always show the error toast, it's missing on some pages.

I also found that if you keep navigating between menus on the sidebar after your token is expired, yoou will end up with a complete white page at some point.

ya a redirect to login will probably be easiest. also we should set a minimum on the token expiry, like 1 minute, because if you set it to 1 second, you've essentially locked yourself out of your account lol
