How to pass Bot instance into middleware?

[sdmway]

Hello, how can I pass a bot object in middleware so I can use bot methods?

My goal is to write a Subscription Checker middleware. So, on each incoming request, it should get the user with bot.get_chat_member() and then, if the user status == 'left', don't handle that request. Thanks!

class CheckSubscriptionMiddleware(BaseMiddleware):
    async def __call__(self, handler: Callable[[types.Message, Dict[str, Any]], Awaitable[Any]], event: types.Message,
                       data: Dict[str, Any]) -> Any:
        user = await bot.get_chat_member(chat_id="example", user_id=event.from_user.id)
        if user.status == 'left':
            return await event.reply("You are not subscribed")
        await handler(event, data)

Bot instance is available in the context data:

bot = data["bot"]
