Python multiple inheritance, standard class with dataclass. (Obtain methods from standard classes and definition from dataclasses)

Question

I have a code with responsibility division:

1. Standard classes which are getting they defenition (inherit) from a dataclasses.
2. Dataclasses themselves.

How I can combine a default class with dataclass to get methods from class and "entity" (self definition) from a dataclass?

Currently I'm getting an error.

Code:

# data_classes.py
from dataclasses import dataclass


@dataclass(slots=True)
class User:
    tg_user_id: int


@dataclass(slots=True)
class NewUser(User):
    username: str
    gender: str
    age: int
    location: str
    comment: str
    moto_drive_style: str
    moto_type: str
    moto_hp: int
    moto_brand: str

#classes.py
import data_classes


class User(data_classes.User):
    __slots__ = ('_cursor', 'last_function', )

    def __init__(self, tg_user_id: int):
        super().__init__(tg_user_id)
        self._cursor = GLOBAL_CONNECTION.cursor()
        self.last_function = None

    def __repr__(self):
        return {'tg_user_id': self.tg_user_id}

    def _convert_profile_text(self) -> dict:
    """
    Should be executed after db insertion
    """
        # noinspection PyUnresolvedReferences
        converted_data_with_none = {
            # Don't forget to use parse_mode="HTML" if you are using links
            'Имя': f"<a href='tg://user?id={self.tg_user_id}'>{self.username}</a>",
            'Пол': self.gender,
            'Возраст': self.age,
            'Откуда': f'{self.country}, {self.city}',
            'Комментарий': self.comment,
            'Стиль вождения': self.moto_drive_style,
            'Класс мототехники': self.moto_type,
            'Лошадиные силы': self.moto_hp,
            'Марка и модель': self.moto_brand,
        }

        return {k: v for k, v in converted_data_with_none.items() if str(None) not in str(v)}

    def show_profile(self, show_to_id: int, ) -> MessageId:
        ...


class NewUser(User, data_classes.NewUser):
    def __init__(self, tg_user_id: int):
        super().__init__(tg_user_id)
    ...
