EasySocial : app 'Group Blog' links with EasyBlog

Hello

I planned to buy the app 'Group Blog' but I am not 100% sure to understand the feature : "to create your blogpost from any of your EasySocial’s group pages. The created blog post will be linked to your EasyBlog’s page"

The screenshot seems obsolete and I can not see the link between ES/blog post and EB.
Is it a 2-side link, I mean
- from a ES/Group, I want to see all the blogposts I created
- from the EB page/Blog, can I see all the blogpost created in ES ... and if yes, can I see the Group where I created it?

Maybe clearer with an up-to-date screenshots?

Thanks
Henri
