Is there any way to instruct the assistant during the chats?

Basically, I am using assistants v2, and no matter what I do, it does not follow the rules from my database and instructions; it always gets some data wrong. I tried setting the temperature, but no luck. For example, I ask the agent to only return real estate properties like apartments, but it returns terrains and houses. Another example is that I specifically instruct it to get the photos from the property code, but it still always gets pictures from other codes.

I was wondering if I can correct it while chatting and improve it through human interactions?
