How to set country specific QML Maps locales?

[UxoriousGhost]

When I set the locale from Plugin as "en_IN", the maps are still showing US specific Maps. Please help me out to display country-specific maps.
I'm currently setting locale as follows:

Plugin {
            id: mapPlugin
            name: "mapboxgl"
            locales: "en_IN"
//            locales: ["fr_FR","en_US"]
            PluginParameter {
                name: "mapboxgl.access_token"
                value: ""
            }
        }
