How to add callback button with show_snackbar?

Question

Python

The button with show_snackbar does not work, there are no errors, just an endless loading when you click on the button
Need help, code snippet below, if it is not enough and you need something else, write

elif body.lower() == "":
          keyboard = VkKeyboard(one_time=False, inline=False)
          keyboard.add_button("кнопка1", color=VkKeyboardColor.POSITIVE)
          keyboard.add_button("кнопка2", color=VkKeyboardColor.POSITIVE)
          keyboard.add_line()
          keyboard.add_button("кнопка3", color=VkKeyboardColor.PRIMARY)
          keyboard.add_line()
          keyboard.add_callback_button(label='Покажи pop-up сообщение', color=VkKeyboardColor.SECONDARY, payload={"type": "show_snackbar", "text": "Это исчезающее сообщение"})
          keyboard.add_openlink_button("кнопка5", "-", payload=None)
          vk.method("messages.send", {"peer_id": id, "message": "пункты", "keyboard": keyboard.get_keyboard(), "random_id": random.randint(1, 2147483647)})
