I followed the [AWS self-host documentation](
https://www.medplum.com/docs/self-hosting/install-on-aws#configure-your-name-servers) and hosted a Medplum server/app with a fresh domain. Now I'm looking into how to host Medplum under our main company domain. Our main domain uses Namecheap DNS. The official documentation recommends AWS Route 53. Since we already set up our company email and many other things with Namecheap DNS, I don't want to migrate. Are there any guides/documentation available for configuring a name server other than Route 53 for AWS hosting? Thanks!
