Use wildcard subdomains on Netlify

Question

I'm using a react application which I deploy on netlify and make accessible via a specific subdomain (app.domain.com).

Now I would like to create separate subdomains for each of my customers (customer1.domain.com, customer2.domain.com etc.). However, I want to use the same react application (same git repository / same branch) for all of these subdomain. The react application logic should decide what content to display on the different subdomains.

My questions are: - What do I need to configure in the netlify dns panel? - What do I need to configure on namecheap?

Looks like this is possible on Netlify; however, it currently requires a pro plan as well as custom approval from Netlify's Support Team on a per-site basis, as indicated by Netlify's Director of Support on this thread
