Submodule for group entities does not work with new versions of group module

Support for Group 3 added in latest stable release 1.0.8

Thank you for your work.
It looks like $group_content_enabler in "$group->addRelationship($replicate, $group_content_enabler);" is NULL so its not creating the relationship and throws and error "Drupal\Component\Plugin\Exception\PluginNotFoundException: Plugin ID '' was not found. in Drupal\Core\Plugin\DefaultLazyPluginCollection->initializePlugin() (line 79 of /var/www/clients/client1/web19/web/web/core/lib/Drupal/Core/Plugin/DefaultLazyPluginCollection.php)."

Thank you for the bug report webberly and your patience, I've made a new release 1.1.0 that should resolve all the issues with Group 3.
