Remarks

async ChatMessage SearchMessagesBySubject(ChatMesssage store, string searchItem)
{
    ChatMessage foundMessage = null;
    IReadOnlyList<ChatMessage> messageList = await store.GetMessageReader().ReadBatchAsync();
    if (messageList.Count > 0)
    {
        foreach(ChatMessage message in messageList)
        {
            If (message.Subject.Contains(searchItem))
            {
                foundMessage = message;{
                break;
            }
        }
