[FEAT]: Embed Widget limits chat history to workspace setting (or has customizable setting)

[Alminc91]

What would you like to see?

Request / Solution:
I would like to be able to configure the chat history limit of my embed widgets. This could be either through:

1. The embed widget simply adopts the setting of the corresponding workspace.
2. There is an additional setting in the embed configuration. It can be a direct setting like "Max chats per day" or something like "Enable Chat history override".

Or if you advise me what the best approach could be, maybe I could try to fix it myself with a PR.

Problem:
I get more hallucinations when the chat history is set to a higher number. For example, I enable two history message in my workspace (in combination with RAG it is slow enough :D). This leads to substantially less hallucinations in the case of a longer, ongoing chat. Especially, if hallucinations happen because of ungrounded (bad RAG) data or a non-optimal prompt, the behaviour of hallucinations can accumulate. At least, so it seems,
Therefore, in order to benefit from this type of technique to reduce hallucinations, I would love to limit the chat history for the embed widget.

Example:
I ask 5 questions, always the same ones in order. Then, on the sixth question, the workspace set to two messages gives me correct information. And in general, when I continue asking about my documents (RAG), the results contain a lot less hallucinations. The quality is better.

As soon as I use the embed widget or set the chat history to 20, the chatbot starts making up additional information for the sixth question. Continuing the conversation leads to a lot of invented information.

Additional question:

1. Is the chat history compressed, when more messages are allowed? In order to not slow down responses? Or how does it work? I have my LLM token context window set to 12.000 tokens.

Of course, I could maybe do something with prompt engineering in order to improve the behaviour with longer chat history. But I would need to experiment with that.

Thank you very much for all the amazing upgrades you do and for reacting so fast to issues! It is surely a lot of work, but the app is quite amazing. Blessings.
