If you don't use this feature of these operators, use `secretKey: credentials` in the spec of these operators to ensure that the service credentials retain any JSON data as it is. **We recommend that you use `secretKey`, even when credential metadata is available to reduce the overhead of interpreting parsing multiple JSON attributes.**

 The `provider` section specifies details of the provider subaccount linked to this application, while `globalAccountId` denotes the global account in which the provider subaccount is created.
