Mocking first response for chat agent

[ban1989ban]

I need to make a voice agent and want to mock first response of agent
user: Hello
Assistant : --- Hard coded respomnse -- -
User

and soon

I want to do this and store this in the session memort of ADK. how to do?

async def run_prompt(session: Session, new_message: str, hardcode_first=False):
  content = types.Content(
      role='user',
      parts=[types.Part.from_text(text=new_message)]
  )
  print('** User says:', content.model_dump(exclude_none=True))

  if hardcode_first:
      # Create a hardcoded response event

        event = Event(
            invocation_id='invocation',
            author=app_name,
            content=types.Content(role='model', parts=[types.Part.from_text(text="Hello Ankit, My name is Neha, and I'm a study counsellor . How can I help you?")]),
        )
        await session_service.append_event(session=session_11, event=event)

        return

  # For subsequent messages, proceed with normal processing
  async for event in runner.run_async(
      user_id=user_id_1,
      session_id=session.id,
      new_message=content,
  ):
      if event.content.parts and event.content.parts[0].text:
          print(f'** {event.author}: {event.content.parts[0].text}')

Tried using this but not working
