How can i add a new field value in existing Array of algolia indices. I have created a new indices for ex in below image
with this method from this link https://stackoverflow.com/a/49607796/4232013
user_details.put("user_username", username);
user_details.put("user_email_id", email);
user_details.put("user_id", UUID);
Client client = new Client(ApplicationId, AlgoliaKey);
Index index = client.getIndex("Users");
List<JSONObject> array = new ArrayList<JSONObject>();
array.add(new JSONObject(user_details));
index.addObjectsAsync(new JSONArray(array), null);
