Telegram Mini App无法向Bot传数据：内联按钮适配疑问

我使用python-telegram-bot库开发Telegram Bot并对接Mini App，目前小程序可正常启动且能接收Bot发送的数据，但反向传输出现问题：小程序中调用tg.sendData后，Bot中的消息处理器未触发。

更新：我研究了多个Mini App示例，发现将InlineKeyboardButton替换为KeyboardButton、InlineKeyboardMarkup替换为ReplyKeyboardMarkup后，数据传输恢复正常。这是否意味着InlineKeyboardButton无法用于启动Mini App？但我见过部分Bot使用InlineKeyboardButton启动Mini App，是否需要额外配置才能让内联按钮实现数据传输？

Bot代码 #

from telegram import Update, InlineKeyboardButton, InlineKeyboardMarkup, WebAppInfo
from telegram.ext import Application, CommandHandler, MessageHandler, ContextTypes, filters
from telegram_token import TELEGRAM_TOKEN


async def start(update: Update, context: ContextTypes.DEFAULT_TYPE):
    keyboard = [
        [InlineKeyboardButton(
            "🕒 Set time",
            web_app=WebAppInfo(url="https://testsite.com/time-widget/test.html?time=9:33")
        )]
    ]

    await update.message.reply_text(
        "Press this button to set time:",
        reply_markup=InlineKeyboardMarkup(keyboard)
    )


async def handle_web_app_data(update: Update, context: ContextTypes.DEFAULT_TYPE):
    data = update.message.web_app_data.data
    await update.message.reply_text(f"Received data: {data}")


def main():
    application = Application.builder().token(TELEGRAM_TOKEN).build()

    application.add_handler(CommandHandler("start", start))
    application.add_handler(MessageHandler(filters.StatusUpdate.WEB_APP_DATA, handle_web_app_data))

    application.run_polling()


if __name__ == "__main__":
    main()
