Cloudflare Tunnels + Access for subdomains?

Hi, I’m using a tunnel for a subdomain, which is also being protected by CF Access, but inside this subdomain I have some redirects when I move around my platform, for example,

(Using dashes instead of dots because this post doesn’t let me add URLs)
Main: dashboard-domain-com
Other sub-subdomains: admin-dashboard-domain-com for visiting my application’s profile,
my-dashboard-domain-com, etc.

I can’t access for example admin-dashboard-domain-com because I don’t have a DNS record for that one. How can I “map” every subdomain (*.subdomain-domain-com) using the same tunnel? Also, is it possible to use CF Access for every sub-subdomain without needing to authenticate everytime I move around (Visit different subdomains)?
