Define "spawn point" for a map?

I’m currently working on a project using map and I was wondering if there is a way to define the “spawn point” of the map ?

Basically, it goes like this (I intentionnaly zoomed out but red rectangles are initial zoom since I used zoom=11 as parameter, and don’t mind all the dots in the desired spawn, its Work In Progress :smile:):

From the doc it seems like there is no parameter for this.
