Cloudflare CNAME custom domain name

Didn’t see any Cloudflare-specific DNS instructions. This is all I’ve found: https://localxpose.io/docs/tutorials/create-a-custom-domain-name

Have added my domain as CNAME www and @. Not a DNS expert, but the latter shows a warning about CNAME flattening.

Trying to setup a custom domain name to do something along the lines of loclx tunnel http --reserved-domain example.com.

dig CNAME www.example.com shows the correct record per the gui and cli. TLD returns Cloudflare’s DNS servers: anita.ns.cloudflare.com. dns.cloudflare.com.

Thanks in advance!
