Passing Payload to Example in Mock GET Call

I have a mock server GET call with one Example. I want to be able to run the GET call and pass the response payload to the Example dynamically so that the response in the GET call matches the payload I passed to the Example.

I put the {{$body}} variable in the Body of the response of the example and added the “x-mock-match-request-body” header and set it to “false”. Assuming this setup is correct, I don’t understand how to make the GET call to pass the payload to that variable.

Please help!
