Change scope to billing account

[aishvaryaps]

I have deployed the azure_billing_exporter using docker commands. Currently, I am using the default AZ API query mentioned in the documentation ie;
{
"type": "ActualCost",
"dataSet": {
"granularity": "None",
"aggregation": {
"totalCost": {
"name": "PreTaxCost",
"function": "Sum"
}
},
"grouping": [
{
"type": "Dimension",
"name": "ResourceGroupName"
}
],
"sorting": [
{
"direction": "descending",
"name": "PreTaxCost"
}
]
},
"timeframe": "Custom",
"timePeriod": {
"from": "{{ CurrentMonthStart }}",
"to": "{{ TodayEnd }}"
}
}

I want to fetch the response at the billing account level. How can we change the scope from subscription to billing account? Is that possible?

So basically I want to see the results for
https://management.azure.com/providers/Microsoft.Billing/billingAccounts//providers/Microsoft.CostManagement/query?api-version=2022-10-01
Where can I change the API URL ?
