Tutorial - Editing video templates for maps

I’m looking for a tutorial on editing the video template for the South African map kit.

I’m new to after effects as well and I figured out how to make kml file and how to work with google earth studio, but I need to also know how to edit the video template - where I can find a how to guide? Youtube tutorial?

I think you should try with google it can be your best helping hand to change/customize your location map.
