@gabe-lyons should we also include fetching an application? It was in the feature guide but not here

query getApplication {
  application(urn: "urn:li:application:engineering") {
    urn
    properties {
      name
      description
    }
    children {
      total
    }
  }
}

@gabe-lyons this is good to go from my side; will defer to you if you want to include the URN lookup example in the API guide or not
