Fetch recently created budget thrugh API

I created this budget in the budget management  and I need to fetch these data to be used for cash flow analysis in our application. 

I found the Account Budget api at  `https://developer.myob.com/api/myob-business-api/v2/generalledger/accountbudget/` but the data i got in this endpoint is not the data of that budget i created. in fact, even if I delete that `Test budget` I still get these data (see file attached).

Also, if this is the only way, can somebody guide me how should I customize the data to fetch e.g. Jan 2023 to Dec 2023  or just june 2023, etc...

As I check at the api documentation for accountbudget endpoint, no specific instruction how to add query arguments to this specific endpoint.

Thank you in advanced.
