I tried to initialize the tool with

        pdf_tool = PDFSearchTool(
            config=dict(
                llm=dict(
                    provider="azure_openai",
                    temperature=0.0,
                    api_key=os.getenv("AZURE_OPENAI_API_KEY"),
                    azure_endpoint=os.getenv("AZURE_OPENAI_ENDPOINT"),

But that raises a schema.SchemaError: Key 'llm' error: Wrong keys 'api_key', 'azure_endpoint', 'temperature'

Thanks for any help.
