Test app consent revocation in sandboxing

I followed the method outlined in Apple's documentation to test "Revocation of Consent." Our server received the notification sent by Apple, but the parsed data only contains the following content (some data has been modified for privacy, but the fields remain unchanged):

{ "receiptType": "Sandbox", "bundleId": "com.xxx.xxxxx", "receiptCreationDate": 1764932591296, "requestDate": 1764932591296, "originalPurchaseDate": 1375340400000, "originalApplicationVersion": "1.0", "appTransactionId": "705020051250081000", "originalPlatform": "iOS" }

How can we identify that "a parent/guardian has revoked authorization for a specific user"? We are unable to determine which minor user should be restricted from using certain features of our app.

I hope to receive a prompt response from Apple's technical experts!
