Streamlit is an open-source Python library that makes it easy to create and share beautiful,

--- Optionally, specify your own session_state key for storing messages
msgs = StreamlitChatMessageHistory(key="special_app_key")

--- As usual, new messages are added to StreamlitChatMessageHistory when the Chain is called.
config = {"configurable": {"session_id": "any"}}
response = chain_with_history.invoke({"question": prompt}, config)

why in both places key values are different ?

I'm not sure if I understand what you're trying to ask.

The first one is to store chat messages in Streamlit's session state under the key special_app_key. The second one, session_id is a key inside the session state object(special_app_key) to track and retrieve messages for the session when invoking the chain.
