Java Spring and Mongo - Iterate through a cursor in a document

Question

I'm using the mongo dependency in a Spring java application. I need to iterate through a cursor after I use runCommand.

    MongoDatabase db = mongoClient.getDatabase("database");
    Bson command = Document.parse("{ \"find\": \"collection\", \"filter\": { \"field\": \"value\" } }");
    Document result = db.runCommand(command);
    System.out.println(result)

It returns : Document{{cursor=Document{{firstBatch=[Document{{}}]}}}}

I can access the cursor with result.get("cursor") but it still returns a document. How can I achieve this please?

Thanks!
