dataKey syntax for quoted names?

[tooptoop4]

Sensor for SQS has this section:

          parameters:
            - src:
                dependencyName: test-dep
                dataKey: body
              dest: spec.arguments.parameters.0.value

what dataKey value should i put to extract values eventName and x-amz-request-id from below? i tried on https://gjson.dev/ but couldn't work out the syntax to handle Records part.

Expected values:
ObjectCreated:Put
r6
