Hi Sangeetha,
About your inquiry, I'm afraid that the data returned by the CustomerSyncService is limited to the fields available in the said service. Other more specific details of the entity you are querying, as you have listed, is not supported.
You may instead, refer to the Change History of the Google Ads UI for more detailed information regarding the changes made to your account. I hope this helps.
Thanks and regards,
Peter
