What is the event Schema for CloudFront To Lambda Function URL

I'm using a Lambda function URL as the origin for a CloudFront distribution. FYI the Lambda function uses Go 1.20 (on provided.al2 and Arm64). Seems to work fine, but I CANNOT retrieve query parameters in code when making request, for example "https://www.example.com?test=1234".

CloudWatch logs sample:

Sample of the Object I'm dumping the event into:

type Request struct {
    Context               Context        `json:"context"`
    Version               string         `json:"version"`
    RouteKey              string         `json:"routeKey"`
    RawPath               string         `json:"rawPath"`
    RawQueryString        string         `json:"rawQueryString"`
    Cookies               []string       `json:"cookies"`
    Headers               cli.StringMap  `json:"headers"`
    QueryStringParameters cli.StringMap  `json:"queryStringParameters"`
    QueryString           cli.StringMap  `json:"querystring"`
    RequestContext        RequestContext `json:"requestContext"`
    Body                  string         `json:"body"`
    PathParameters        interface{}    `json:"pathParameters"`
    IsBase64Encoded       bool           `json:"isBase64Encoded"`
    StageVariables        interface{}    `json:"stageVariables"`
}

Though I should switch to this: https://github.com/aws/aws-lambda-go/blob/v1.41.0/events/lambda_function_urls.go#L14C39-L14C39

Yes I have allowed all query strings in my CloudFront Request policy:

I have also removed any CloudFront and Lambda@Edge functions until I get pass this.

Problem is that I'm not sure which event Request format is in use when CloudFront invokes the Lambda Function URL. Any AWS documentation I've read so far has not made it clear. I have multiple choices:

1. https://docs.aws.amazon.com/lambda/latest/dg/urls-invocation.html#urls-payloads
2. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/functions-event-structure.html

I also don't see an official CloudFront event that I can use in the official AWS Lambda Go Package here at https://pkg.go.dev/github.com/aws/aws-lambda-go/events#section-readme.
