Renew session in flask example

It looks like in this example is absent any functionality with the renewing session

for example, if i authorize via auth0 and then remove the session cookie, I will be redirected to the login page, but how to implement functionality to auto-renew session, because i authorized into the my auth0 auth dns

Or maybe problem with setting of auth0 ?

if i go back to
