[slack_bolt] app.event 또는 app.action에서 reply 하기

Reply 로 메세지를 생성하기 위해서는 아래와 같이 thread_ts 를 say로 전달해 주면 된다.

app.event

@app.event("message")
def handle_message_events(body, event, say):
	say({
       "channel": body["event"]["channel"],
       "text": "This is a threaded reply!",
       "thread_ts": body.get("thread_ts", body["event"]["ts"]),  # Use thread_ts if available, otherwise use ts
  	})

app.action

@app.action("action_id")
def button_click(ack, body, say):
    # Acknowledge the action
    ack()
    say({
        "channel": body['channel']['id'],
		"text": "This is a threaded reply!",
		"thread_ts": body.get("thread_ts", body["message"]["ts"]),  # Use thread_ts if available, otherwise use ts
  	})
