Your organization has multiple SageMaker Studio domains (one per department). You want a central proxy app that authenticates users with the company's identity provider and then routes each user to their department's Studio domain. You will store the domain mapping in a DynamoDB table. Which API should the proxy use to send users to the correct Studio domain?

The CreatePresignedDomainUrl API is the correct choice because it generates a temporary, authenticated URL for a specific SageMaker Studio domain. This allows the proxy application to dynamically direct users to their department's Studio domain after authenticating them with the company's identity provider and looking up the domain in DynamoDB. CreateHumanTaskUi and ListHumanTaskUis are used for Amazon Augmented AI (A2I) human review workflows, not for accessing SageMaker Studio domains. CreatePresignedNotebookInstanceUrl is for accessing individual SageMaker Notebook Instances, which are distinct from SageMaker Studio domains.
