    Args:
        knowledge_base_id: Knowledge Base ID.
        region_name: The aws region e.g., `us-west-2`.
            Fallback to AWS_DEFAULT_REGION env variable or region specified in
            ~/.aws/config.
        credentials_profile_name: The name of the profile in the ~/.aws/credentials
            or ~/.aws/config files, which has either access keys or role information

            EC2 instance, credentials from IMDS will be used.
        client: boto3 client for bedrock agent runtime.
        retrieval_config: Configuration for retrieval.

    Example:
        .. code-block:: python

            from langchain_community.retrievers import AmazonKnowledgeBasesRetriever

            retriever = AmazonKnowledgeBasesRetriever(
