Does VNC browser rendering work for Cloudflare Tunnel installed on MacOS?

I have Screen Sharing enabled through the default macOS screen sharing option in system preferences. I have Cloudflare Tunnel installed on the mac that I want to VNC into

My config.yaml has the following: hostname: and service: vnc://

I also enabled an app policy for this subdomain in the Zero Trust dashboard and enabled VNC browser rendering

However, when I visit the URL, it just doesn’t load. Anything that I’m doing wrong?

Whenever I visit the above IP address on the Mac which has Screen Sharing, I get this messaged: “You cannot control your own screen”

Not sure if this is the reason why it’s not working and what to do to fix this
