psycopg2.errors.UndefinedTable: relation "django_content_type" does not exist

The issue's title is the error I get when attempting to migrate this app in project using Django 2.2.

After adding django-notifications-hq==1.6.0 to requirements.txt, and 'notifications', to settings.INSTALLED_APPS, I execute python manage.py migrate.
All other migrations work well, but not notifications.
Running python manage.py showmigrations shows:

...
notifications
 [ ] 0001_initial
 [ ] 0002_auto_20150224_1134
 [ ] 0003_notification_data
 [ ] 0004_auto_20150826_1508
 [ ] 0005_auto_20160504_1520
 [ ] 0006_indexes
 [ ] 0007_add_timestamp_index
 [ ] 0008_index_together_recipient_unread
...

Does anyonw else have this issue when trying to use the module?
Does it migrate well for everyone?
I'll say that I tried using django-activity-stream, which your project seems to be based on, and it throws the same error. However theirs only supports 1.x versions of Django.

I would appreciate any and all help in stomping this issue.
Thanx.
