Responsiveness and end_call parameter for AsyncRetell?

[minor]

I have the following to send a call through Retell to another outbound number:

retell_client = AsyncRetell(api_key=os.getenv("OPPENHEIMER_RETELL_API_KEY", ""))

await retell_client.llm.update(
        llm_id=RETELL_BOOK_APPT_LLM_ID,
        general_prompt=CUSTOM_PROMPT,
        model="gpt-4o-mini",
    )

response = await retell_client.call.create(
        from_number=RETELL_AGENT_NUMBER,
        to_number=CUSTOM_OUTBOUND_AGENT,
        override_agent_id=RETELL_BOOK_APPT_AGENT_ID,
    )

Two questions:

1. Is there a way to set this call/agent up with a responsiveness parameter: (

   retell-python-sdk/src/retell/types/agent_update_params.py

   Line 85 in f546d9e

   end_call_after_silence_ms: int

   )

2. Is there a way to add an "end_call" parameter that will automatically end the call if it exceeds a certain amount of time (i.e. 10 minutes)?

Thanks in advance.
