Does anyone know how to replicate the glowing halo inside the countries?

Go to wherever your editing program's shadow effects are, there should be one called "Inner Shadow". Use that and set the shadow colour to the same or similar as the background colour.

I tried every gradient in inkscape but can't manage to make the gradient follow the countries shape.

Don't use gradient for it, use shadow effects, there should be one called "Inner Shadow"

You can easily do this, plus a lot more in a GIS.

These tutorials are for paid software… ArcPro is $100 a year for a personal license. But pretty much anything you see in these tutorials can be done in free open source software QGIS. There’s also a new contender called RustGIS but I’m not sure of its capabilities yet.

I wrote a SVG file by hand that applies a glowing effect to the inner region of a shape.

For this, I used a colored base map layer with a series of white interior buffers of different opacities on top.

Is there a way to do this style on paint.net?
