Why doesn't the lower method work in vkbottle?

Question

Python

Hello! For some reason I can't use the lower method in VKBOTTLE.

from vkbottle.bot import Bot, Message

bot = Bot('token')
@bot.on.message(text='start', lower=True)
async def bdate(ans: Message):
await ans("hello")

bot .run_forever()

KeyError: 'lower'

Answer 1

This is an example for old versions of the bottle, in new ones it looks like this
bot.labeler.vbml_ignore_case = True

Answer 2

Because such a custom_rule is not defined by default. If you want to use lower, then you need to define this rule first.
