In the file packages/examples/sdk-frontend-react/src/app/ChatUITest/ChatPreviewList.tsx, I found the following issues:

1. Typo in the JSX syntax with the incomplete input tag:

   <input
     type="text"
     onChange={handleAddressChange}
     value={address}
     style={{ width: 400, height: 30 }}  {/* Missing closing angle bracket */}

2. The onChatSelected, onUnreadCountChange, onLoading, onPaging, and onPreload props of ChatPreviewList component have incorrect arrow function declarations with multiple parameters. It should be wrapped in a single object like this:

   onChatSelected={(chatid, chatParticipant) => { console.log("Chat id: ", chatid, chatParticipant) }
   // Should be changed to
   onChatSelected={({ chatid, chatParticipant }) => { console.log("Chat id: ", chatid, chatParticipant) }

In the file packages/examples/sdk-frontend-react/src/app/ChatUITest/ChatProfile.tsx, I found one issue:

1. The chatId prop in the ChatProfile component is commented out, and you should remove the comment to make it active.

In the file packages/uiweb/src/lib/components/chat/ChatPreviewList/ChatPreviewList.tsx, I found the following issues:

1. The addChatItems function is missing a closing bracket.
2. Syntax error in the removeChatItems function where the closing bracket is misplaced after the filter method.
3. Syntax error in the transformGroupCreationStream function where the closing bracket is misplaced after the chatMsg object.
4. Syntax error in the transformStreamMessage function where the closing bracket is misplaced after the modItem.chatParticipant = profile.groupName;.
5. Similar syntax errors in various parts of the file such as missing closing brackets, misplaced closing brackets, and incomplete functions.

I recommend fixing these issues before proceeding. Let me know if you need further assistance.
