Retrieve message history

Hi, I found there is a similar question about retrieve message history from a certain time. And also notice the feature request is not achieved. Thus I started a new one.
My question is, is there any way to retrieve all messages, no matter the session, in unity/docker?

Yes you can retrieve all the chat messages;

When listing messages (up to 100 per API call), a cursor is returned that you can use to ask for the next page of results. You can keep doing this until there is no cursor. We’ll be updating our code examples on the page to include how best to achieve this.
