How to add new sections in Confluence?

Hi there,

Im trying to add a new section in Confluence, much akin to the Teams Calendar app that comes with Confluence Datacenter licenses.

Adding a new item in the navbar is pretty easy and explained by the documentation - although I do not grasp how to manifacture the page I will be linking and displaying content on.

I do not want to link to a normal confluence page, space or existing functionality, but a entirely new one.

Any hints or pointers how to accomplish this are welcome :wink:
