How I can Highlight the region on Globe instead Country

I’ve just make an ThreeJS globe, that currently highlight the country using click data-path"travel/US", but now I’ve decide to highlight the region instead country. Is there any way to highlight the region.

GIthub Repo: GitHub - malikfaizanhaider/Interactive-globe: I Have to create this WebGL prototype of a globe made of evenly spaced dots that light up as you fly to any of the 236 countries on the planet.
