How to check Quota exceeded in CloudKit

I want to prompt users when their iCloud storage quota is full. My test device's iCloud space is full, and when subscribing to the NSPersistentCloudKitContainer-eventChangedNotification event, events exceeding the quota will not be passed to the application at runtime.

When I tried to add data to Core data using NSPersistentCloudKitContainer, I got an error:

<CKError 0x600000c15890: "Quota Exceeded" (25/2035); server message = "Quota exceeded"; op = 1ECF73B9554DF79F; uuid = 34D12DF0-A307-49EB-AD3A-BB646FF66F54; Retry after 316.0 seconds>}>

My iCloud storage space is full, but I am unable to retrieve the 'Quota exceeded' error.I have written a demo, please help me fix the issue.

I posted about the same issue before and also filled feedback. But this is still an issue: https://developer.apple.com/forums/thread/830420
