How to get the "@odata.type" entries in the serialized content?

As is, the generated code creates a body that looks something like this

{
	"ExtractionRequest": {
		"ContentFieldNames": [
			"RIC",
			"Round Lot Size",
			"ISIN",
			"Currency Code"
		],
		"IdentifierList": {
			"InstrumentIdentifiers": [
				{
					"Identifier": "IBM.N",
					"IdentifierType": "Ric"
				}
			]
		},
		"Condition": {
			"FixedIncomeRatingSources": "None"
		}
	}
}

But the API I am using will only work if I POST it something like this

{
	"ExtractionRequest": {
		"@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.TermsAndConditionsExtractionRequest",
		"ContentFieldNames": [
			"RIC",
			"Round Lot Size",
			"ISIN",
			"Currency Code"
		],
		"IdentifierList": {
			"@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
			"InstrumentIdentifiers": [
				{
					"Identifier": "IBM.N",
					"IdentifierType": "Ric"
				}
			]
		},
		"Condition": {
			"FixedIncomeRatingSources": "None"
		}
	}
}

For reference the API I am using is found at “https://selectapi.datascope.refinitiv.com/RestApi/v1/Extractions/$metadata”

The serializer seems to be the problem for some reason 😓 will look into it tomorrow again
