+      Returns a one-click AWS CloudFormation quick-create URL (with a server-side

+      connector role in their own AWS account. The template bucket stays private —
+      presigning is done with the service execution role — so no public S3 endpoint
+      is required and the customer needs no S3 access of their own.
