HTTP 403 Forbidden from ZFS screeningRequest API

I am working on a WorldCheck One ZFS Zero Footprint Screening pilot. I dug through all of the emails, downloaded all of the documentation and Postman documents, and started writing some code to support the custom API authentication system and get data coming back.

I am able to call all of the following APIs perfectly fine with no trouble:

https://rms-world-check-one-api-pilot.thomsonreuters.com/v1/reference/countries
https://rms-world-check-one-api-pilot.thomsonreuters.com/v1/groups
https://rms-world-check-one-api-pilot.thomsonreuters.com/v1/groups/5nzbfkcaflyi1en8ajboby9dh
https://rms-world-check-one-api-pilot.thomsonreuters.com/v1/groups/5nzbfkcaflyi1en8ajboby9dh/caseTemplate

However, when I try to call this API for the ZFS (Zero Footprint Screening), it fails with a 403 Forbidden error:

https://zfs-world-check-one-api-pilot.thomsonreuters.com/v1/cases/screeningRequest

Can somebody check why the access to the ZFS API is blocked and help me fix it?

I am calling with the following request payload:

{
    "groupId": "5nzbfkcaflyi1en8ajboby9dh",
    "entityType": "ORGANISATION",
    "providerTypes": [
        "WATCHLIST"
    ],
    "name": "Google",
    "secondaryFields": [
        {
            "typeId": "SFCT_6",
            "value": "USA"
        }
    ]
}

I put some detailed debug logs below (sensitive items REDACTED):
