how to make conversationalretrievalchain to include metadata in the prompt using langchain with chromadb to make the LLM aware of metadata?

im trying to do a bot that answer questions from a chromadb , i have stored multiple pdf files with metadata like the filename and candidate name , my problem is when i use conversational retrieval chain the LLM model just receive page_content without the metadata , i want the LLM model to be aware of the page_content with its metadata like filename and candidate namehere is my code

conversation_chain=ConversationalRetrievalChain.from_llm(        llm=llm,        retriever=SelfQueryRetriever.from_llm(llm,vectorstore,document_content_description,metadata_field_info),        memory=memory,        verbose=True,    )

and here is my attribute info

metadata_field_info = [    AttributeInfo(        name="filename",        description="The name of the resumee",        type="string",    ),    AttributeInfo(        name="candidatename",        description="the name of the candidate",        type="string"    )]
