Concerns Regarding CoreData Lightweight Migration Impact on CloudKit Schema Deployment

Question

I've performed a lightweight migration on CoreData to add a new query index. Testing locally, the migration appears to work fine. However, I'm concerned about the data schema in CloudKit.

Based on information from Releasing new Core Data Schema to iCloud production , I executed the following code to ensure schema initialization for CloudKit:

let options = NSPersistentCloudKitContainerSchemaInitializationOptions()
try? container.initializeCloudKitSchema(options: options)

Despite this, when deploying the schema change from development to production, there seems to be no changes. Is this expected behavior, or have I missed some steps?

Could it be possible that adding a new query index in CoreData does not affect the data schema in CloudKit?

Thank you.
