Way to add Indoor vector maps in MazeMap system

We have been given a task to create an indoor wayfinding app for our university.

So far we have chosen Android as our platform and are using Android-Studio as our IDE. Plan is to create a simple android app that runs MazeMap as Webpage in it.
Since creating Navigation manually seems to hard for us we have found solutions by MazeMap’s Developer API.
While their documentation explains quite well how their navigation works, we haven’t found an explanation on how to integrate the Vector floor plans that we have created, to start mapping the doors and pathways on. Does anyone have tips or ideas on how it could be achieved, or maybe guide us on more achievable path?
