Hi @2_2,

Yes, you need to customize UIKit.

1. I didn’t get what exactly you want in this question. But If you want to change the current UI message, you need to customize MessageCell.

2. For this, you need to customize MessageCell.

3. UIKit already has a [message search function](https://sendbird.com/docs/uikit/v1/react/guides/message-search#1-message-search).

4. It shows a read receipt in UIKit. One tick → sent, Double tick-\>Delivered, Double-tick with green → Message read.

5. With webhooks turned on in your Sendbird application, Sendbird will send HTTP `POST` requests to your server when selected events occur within the application. Let’s say If `user:block` event is turned on, once any user blocked others, Sendbird will send HTTP `POST` requests to your server’s endpoint with data that shows which users block which user.

6. [This sample](https://github.com/sendbird/sendbird-uikit-react) is react UIKit sample. Please download and start customizing. If you failed to customize, please file ticket from your dashboard.
