How to run custom reports in FCCS using rest API

We have custom reports build under Dashboards Reports section. We want to execute them via rest API. I have tried the rest API provided under

But it not working as the API expected Report group name and our custom reports are developed directly in the dashboard with no group name associated to it.

Tried POST https://{pod-name}.epm.{datacenter}.oraclecloud.com/epmrestapi/rest/v1/applications/{application-name}/jobs but this is also giving 400 bad response.

{ "jobType": "REPORT", "jobName": "Execute Report", "parameters": { "report_name": "Consolidated Balance Sheet", "report_format": "XLSX", // Options: PDF, HTML, XLSX "pov": { "Scenario": "Actual_USGAAP", "View": "FCCS_Periodic", "Entity":"911", "Year": "FY25", "Period": "P4" // Add other dimensions as needed } }}
