Moving from Vercel to Netlify (using Cloudflare DNS)

I bought a domain through Namecheap but set the nameservers to Cloudflare (so I get access to their DDOS captcha protection page)

I currently have the following records for Vercel set:
A coinrotator.app 76.76.21.21
CNAME www cname.vercel-dns.com

My primary domain is coinrotator.app and I want www.coinrotator.app to resolve to coinrotator.app

How do I achieve this? Cloudflare has no ANAME or ALIAS records, but from their documentation, it seems they do support CNAME flattening CNAME flattening · Cloudflare DNS docs

@mayrsascha You may have already encountered it, but the applicable documentation is here:
