Honestly the easiest way to do this is automation against either the firewall, a SIEM that the firewall is forwarding to, or an EDR that is deployed on all of your endpoints. You need to have the capability to validate whether the URL in question is actually being hit by any of your endpoints, something that the firewall itself doesn't natively provide short of searching through the URL logs and seeing if you have any hits. Something to be mindful of when doing this is your logging duration, as inadequate logs could quickly start causing issues if you start removing URLs that are actually still needed.
