How Team has defined the names of the Notion module?

Hi, when you add a Notion module, you get the choice between these actions :

and when you look at Notion API, you have theses actions : (source: )

Why do they look so different ? Why do they have different names and are organized in a different way? Regards

These are all decisions one makes when designing an app. The names of the modules are related to the api quite closely. The question I have is the modules themselves are quite complex to use as they have these internal object IDs that have to be searched for rather than just showing the object names. The notion app is one of the more complex apps.

Is there somewhere a mapping between the 2 ? Notion Module
Notion API

I am interested to know what API I am actually using so that I can better understand and ref to the proper documentation when needed
