Load the GeoJSON in a Python SOP, read each feature’s country name and its Polygon or MultiPolygon coordinates, convert longitude–latitude to planar XY to create points and closed polygon primitives, tag primitives with attributes for the country name, a numeric country_id, and whether each ring is an outer boundary or a hole, use a Boolean SOP to subtract rings marked as holes per country, then assign a unique color driven by the country_id (or name) so all pieces of the same country share one color, optionally pack by country_id to make each country a single selectable piece.
