How to allow customers to use custom domain?

For example, I have my application hosted on Cloudflare worker with domain dayschedule.com and each customer get their subdomain on signup with wildcard routing - For example vikash.dayschedule.com

How can I use Cloudflare to allow our customers to map their domain via CNAME mapping?

For example -

vikash.com > vikash.dayschedule.com
alpha.com > alpha.dayschedule.com

I will use D1 to store mapping when reigstered by customers, also the HTTPS expected to work on all links.

Specifically, using Workers with Cf for SaaS requires a specific setup with routes: https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin/
This will issue a cert. for each custom hostname, allowing https to work. The only thing to keep in mind is they can only do it on their apex (alpha.com), if they are using a DNS Provider that supports CNAME on apex, like Cloudflare, or Hurricane Electric. Otherwise, apex proxying is an enterpise addon (or they'd have to pick a subdomain like scheduling.alpha.com).
You get 100 custom hostnames for free, any over that is $0.10/per hostname/per month
