bot.on('chat_member', async msg => {
console.log(msg,'dsadsa')})
嗨，此事件在此 lib node-telegram-bot-api中不起作用
但我不知道为什么？我看到chat_member代码中没有
`on(event: TelegramBot.MessageType | 'message', listener: (message: TelegramBot.Message, metadata: TelegramBot.Metadata) => void): this;
on(event: 'callback_query', listener: (query: TelegramBot.CallbackQuery) => void): this;
on(event: 'inline_query', listener: (query: TelegramBot.InlineQuery) => void): this;
on(event: 'poll_answer', listener: (answer: TelegramBot.PollAnswer) => void): this;
on(event: 'chosen_inline_result', listener: (result: TelegramBot.ChosenInlineResult) => void): this;
on(
event: 'channel_post' | 'edited_message' | 'edited_message_text' | 'edited_message_caption' | 'edited_channel_post' | 'edited_channel_post_text' | 'edited_channel_post_caption',
listener: (message: TelegramBot.Message) => void
): this;
