Description: 

The Drupal\social_group\SocialGroupHelperService::getDefaultGroupVisibility method was used to find the default visibility for the content visibility field for public, open, closed, and secret groups. These group types are being replaced with flexible groups which take care of their own content visibility.

There's no replacement.
