Which IBM Cloud IAM role grants a user the ability to administer watsonx.data resources including creating engines and catalogs?

The Manager (or Administrator) IAM role in watsonx.data grants full administrative privileges including provisioning engines; registering storage buckets; managing catalogs; and configuring access control. The incorrect options ("Reader role — provides read-only access to all watsonx.data resources", "Writer role — allows creating and modifying data assets but not engines", "Viewer role — allows monitoring dashboards but no configuration changes") are distractors that don't fully capture the concept described.
