I have a working Pages app on Cloudflare that I would now like to protect using ZeroTrust Access. I have set it up, and connected to my Google Workspace, created an Access Group with rules etc.
Reading the Docs I have three questions 1) a Pages app I deploy qualifies as a "self-host" app, right? 2) in the "Add an application" page of Zero Trust UI the "self-hosted" option is greyed out and the tooltip says "...can be added one I have an active Zone on cloudflare" - how do I create an active zone? (doc link?) 3) Then I can use the methods & functions described in https://developers.cloudflare.com/pages/functions/plugins/cloudflare-access/ for my Pages app to get GroupId, etc, right?
