Oracle FUsion Cloud Financial API questions

oing an rest API call to Oracle FUsion Cloud Financial API: Get all asset books. from OFC document https://docs.oracle.com/en/cloud/saas/financials/23a/farfa/op-fixedassetbookslov-get.html, the relative API URL is: /fscmRestApi/resources/11.13.18.05/fixedAssetBooksLOV so using Postman to hit it with Get: https://bdomain.oraclecloud.com/fscmRestApi/resources/11.13.18.05/fixedAssetBooksLOV?limit=100&offset=0 where Bdomain is buisness domain name. I got empty response:

{"items": [],  "count": 0,"hasMore": false,"limit": 100, "offset": 0,

 "links": [  {

      "rel": "self",

      "href": "https://bdomain.oraclecloud.com:443/fscmRestApi/resources/11.13.18.05/fixedAssetBooksLOV",

      "name": "fixedAssetBooksLOV",

      "kind": "collection"}]}

But checked tables that I thought behind API, such as FA_Books, FA_Books_summary etc. There are data populated. Is any specific authorization process need to take to get data ? Normally, such Get call without any data filter should get data back.
