I got TypeError: UserManager.create_superuser() missing 1 required positional argument: 'username'

I want to create super user just from email and password so it should create super user without username. I am using custom user model and when i try to create superuser i got this error TypeError: UserManager.create_superuser() missing 1 required positional argument: 'username'

This is my manager.py file

from django.contrib.auth.base_user import BaseUserManager


class UserManager(BaseUserManager):
    use_in_migrations = True

    def _create_user(self, email, password, **extra_fields):

        if not email:
            raise ValueError('The given email must be set')
        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_user(self, email, password=None, **extra_fields):
        extra_fields.setdefault('is_superuser', False)
        return self._create_user(email, password, **extra_fields)

    def create_superuser(self, email, password, **extra_fields):
        extra_fields.setdefault('is_superuser', True)
        extra_fields.setdefault('is_staff', True)

        if extra_fields.get('is_superuser') is not True:
            raise ValueError('Superuser must have is_superuser=True.')
        if extra_fields.get('is_staff') is not True:
            raise ValueError('Superuser must have is_staff=True')

        return self._create_user(email, password, **extra_fields)
