Why doesn't the messages.getLongPollHistory method return messages from conversations? It returns from PM, but not from conversations. When I write something in conversations (given the admin panel, etc.), it returns:
{"response":{"history":[],"messages":{"count":0,"items":[]},"new_pts ":10005536,"from_pts":10005536,"conversations":[]}}

To get messages from Conversations, apparently, you need to:

1. through messages.getConversations() get a list of all conversations,
   
2. using the messages.getConversationsById() method to get the desired Conversation object , where to find the id of unread messages, for example;
   
3. using the messages.getByConversationMessageId() method to get the messages themselves
