Within the Cloud Playground, due to restrictions in place to prevent abuse of recourses and purchases of services, registering a domain name wouldn’t be something that can be done at this time.
You can find the list of available services and limitations within the following article : https://help.acloud.guru/hc/en-us/articles/360001389256-AWS-Cloud-Sandbox
The link you provided that list AWS Cloud Sandbox available services, have Route 53 listed as an available service.
Based on the error you’re getting this seems to be an IAM restriction, that user does not have privileges to perform / use Route53. Maybe this has to do to the fact that in ‘test / playground’ it would be risky to let people register / buy domains.
