Why does the inline button callback not work via vk_api?

Question

Python

The documentation has already been read hundreds of times. Everything is normally called - the button itself is there. It is clickable, but then no action. Infinite loading and nothing more

import json

import vk_api, vk
from vk_api.keyboard import VkKeyboard, VkKeyboardColor
from vk_api.utils import get_random_id
from vk_api.bot_longpoll import VkBotLongPoll, VkBotEventType

vk_session = vk_api.VkApi(token='token')

from vk_api.bot_longpoll import VkBotLongPoll, VkBotEventType
longpoll = VkBotLongPoll(vk_session, 'groupid')
vk = vk_session.get_api()
from vk_api.longpoll import VkLongPoll, VkEventType

keyboard_1 = VkKeyboard(one_time=False, inline=True)
keyboard_1.add_callback_button(
        label="Кнопка",
        color=VkKeyboardColor.SECONDARY,
        payload={"type": "show_snackbar", "text": "Это исчезающее сообщение на экране"}
        )
        
for event in longpoll.listen():
    if event.type == VkBotEventType.MESSAGE_NEW:
        if event.object.message['text'] == 'Кнопка':
            if event.from_chat:
                 vk.messages.send(
                    keyboard = keyboard_1.get_keyboard(),
                    key = ('key'),
                    server = ('server'),
                    ts=('1'),
              	    message = 'Кнопка:',
                    )

Answer 1

Everything turned out to be much easier. There is a button, but there was no reaction to the answer, so we write:

elif event.type == VkBotEventType.MESSAGE_EVENT:
        vk.messages.sendMessageEventAnswer(
            event_id=event.object.event_id,
            user_id=event.object.user_id,
            peer_id=event.object.peer_id,
            event_data=json.dumps(event.object.payload)
            )

Answer 2

Lay out the code, only then it will be possible to help, most likely your condition is written by type

if a == 'привет':
   wtitemessage(id,'Приветик')

But, the button does not display the text you clicked on, track all user messages, or rather when you click on the button
