Connect Prompt ID to GENERATIONS when integrate Langfuse in LangChain.

[hdp173]

Hello.
I'm integrating langfuse into langchain ChatOpenAI model like this.

....

trace = langfuse.trace(name="trace1")
langchain_callback = trace.get_langchain_handler()
model = ChatOpenAI(callbacks=[langchain_callback], ...)

chain = prompt | model | parser

chain.ainvoke(...)

I'm fetching prompt from langfuse and I want to connect prompt id to GENERATION.
Can you help me how to do it?
Thank you.
Regards.
