How to use route model with mapboxgl ?

[OKIP]

I already managed to create routes for osm plugin but with mapboxgl I get:
error: Cannot route, route manager not set. from the RouteModel.
So how can I set the route manager ?

Solved by using 2 plugins
mapboxgl for Map and osm for RouteModel

Plugin {
    name: "mapboxgl"

    PluginParameter {
        name: "osm.mapping.highdpi_tiles"
        value: true
    }

    PluginParameter {
        name: "mapboxgl.mapping.additional_style_urls"
        value: "mapbox://styles/mapbox/navigation-guidance-night-v3"
    }

    PluginParameter {
        name: "osm.routing.host"
        value: "http://router.project-osrm.org/route/v4/driving/"
    }

    PluginParameter {
        name: "osm.routing.apiversion"
        value: "v4"
    }
}

Plugin {
    name: "osm"
}
