Hi
This document is not for partner, the screen you see it is from back-end ABAP system, which can access by developers or localization team and few case partners have access of it.
You can relate this picture to BC scoping,
This is the same task what which can do on Business Configuration->Implementation Project->Scope, check if your tenant has got google groupware integration.
What you see in picture are Add-on which is not part of standard C4C or ByD product but this could be provided as per the customer requirement.
Regards
Sunil
