FutureOr<Object> onCall(Request request) {
  return Access(
    collection: "<collection>",
    type: type,

    // optional. necessary for some operations
    // you can also use "Query" 
    query: MongoQuery(where.eq("field", "value")),
    
    // optional. necessary for aggregation
    pipeline: AggregationPipelineBuilder(/*stages*/),
    // or pipeline: [{"\$project" : {"_id":0}}]
  );

Using with Query, selector parameter must be mongo db style Map. So must be where.eq("field", "value").map["\$query"].
