Properly Retain Conversation History

[HaroldPetersInskipp]

Description

The current method of saving the conversation history as a flow variable and resubmitting it with each query is less than ideal.

Storing the history of conversation allows for iterative edits on the content provided by the ChatGPT node. However, if possible a true chat conversation stored similarly to the web application could be a more robust way to allow users to create high-quality flows using this node.
