Problem with using method setPaths

[jarikus18]

HI! I can't understand how to use method setPaths.
I wanna update the component and change the lines.

When I try to send new props with coordinates, old coordinates also staying.

`
const PolylineDecorator = withLeaflet(props => {

const { positions } = props;
const polyRef = useRef();

useEffect(() => {
const polyline = polyRef.current.leafletElement; //get native Leaflet polyline
const { map } = polyRef.current.props.leaflet; //get native Leaflet map

L.polylineDecorator(polyline, {
  patterns: props.patterns,
}).addTo(map);

}, [positions]);
return <Polyline ref={polyRef} {...props} opacity="0" />;
});
`
