Python version
3.11.11

Django version
5.1.1

Package version
0.12.0

Current behavior (bug description)

The package crashes during Django app initialization when EXTRA_SETTINGS_VERBOSE_NAME is not defined in settings, with the following error:

AttributeError: 'Settings' object has no attribute 'EXTRA_SETTINGS_VERBOSE_NAME'

This occurs in apps.py where it directly accesses settings.EXTRA_SETTINGS_VERBOSE_NAME without providing a default value or checking for its existence.

Expected behavior

According to the package documentation, all settings should be optional. The app should initialize successfully without requiring EXTRA_SETTINGS_VERBOSE_NAME to be explicitly defined, either by:

1. Providing a default value using getattr(settings, 'EXTRA_SETTINGS_VERBOSE_NAME', 'Extra Settings')
2. Or handling the case when the setting is not defined
