WorkDocs CNAME for custom URL

AWS WorkDocs does not support custom URLs through CNAME records or any other method. The URLs for WorkDocs sites are automatically generated by AWS and cannot be changed or aliased. If you need to have a custom URL for users to access files, one possible workaround would be to create a simple web application that provides a file browser interface and uses the WorkDocs API to interact with WorkDocs. You could then deploy this web application on a domain of your choosing. However, this would require developing and maintaining an additional web application, and there would likely be additional costs associated with hosting and operating the web application.
