Telebot (python): how to kick a user out of a chat?

Question

Python

I'm making a bot. Primary authorization - by phone number. I get the user's phone number, check if it is in the database. I don't know how to throw it out (or not let it write) if it is not in the database.

import config
import getNumber
import telebot
from telebot import types

bot = telebot.TeleBot(config.token)
numId = getNumber.NumberIdentifier()


@bot.message_handler(commands=['start', 'help'])
def send_welcome(message):
    # Получаем номер телефона от пользователя
    markup = types.ReplyKeyboardMarkup(one_time_keyboard=True)
    batton = types.KeyboardButton("Логин по номеру телефона", request_contact=True)
    markup.add(batton)
    msg = bot.reply_to(message, 'Так-с. А вы точно не шпион? Проверю-ка я ваш номер телефона...', reply_markup=markup)
    bot.register_next_step_handler(msg, process_step)


def process_step(message):
    if numId.checkPhoneNumber(message.contact.phone_number)=='bad':
        #Не знаю, как тут прекратить с ним общение
    bot.sendMessage(message.chat.id, 'I am hiding it', reply_markup=types.hide_keyboard)

@bot.message_handler(content_types=["text"])

just when processing each message, check whether the given user is suitable, do not send anything, or send a text that he is not authorized, it is not at all necessary to stop communication. and forbid him to write
