feature request "Renew session button" available within 24 hrs of expiry

[efef]

Some organisations use a very short session time, like 12 hours, their users like to be able to renew and extend the session any time during the day. But the "Renew" should not be visable the first 30 minutes after authentication.

background about 30 minutes:

the application SHOULD show a "Renew" button, starting from >= 30 minutes after
the OAuth authorization (using the browser) took place. The reason for this
30 minutes is that browser sessions in the portal are valid for 30 minutes
in eduVPN/Let's Connect! servers. Renewing before the user is forced to login
again results in getting a session that expires at the exact same time as the
previous one which is confusing to the user when they are trying out the
"Renew" button
