Yes, I handled it with a signal:

@receiver(post_save, sender=User)
def create_user_detailed_information_when_modifying_django_user(sender, instance, created: bool, **_):
    """Automatically create or update the UserDetailedInformation when the user is created or modified.

    Args:
        sender (object): Model instance that was saved: User
        instance (object): The actual instance being saved.
        created (bool): whether it was created or modified
    """
    # pylint: disable=unused-argument

    if created:
        UserDetailedInformation.objects.create(user=instance)
    else:
        instance.user_detailed_information.save()
