Как в эффекте Leaflet.MagnifyingGlass для Leaflet отобразить, имеющиеся уже у меня на карте, маркеры и полигоны

На карте я создал маркеры и полигоны, а также добавил плагин Leaflet.MagnifyingGlass. Но не понимаю, как на это "стекло" добавить уже имеющиеся у меня объекты.

var mapid = L.map('map', {
    center: [51.660781, 39.200296], 
    zoom: 10,
    zoomDelta: 1,
    trackResize: true
});

var nokia_map = L.tileLayer('/static/blog/here.com.terrain/{z}/{x}/{y}.png', {
    minZoom: 10,
    maxZoom: 18,
    subdomains:['a', 'b', 'c'],
    attribution: '© NokiaMap'
}).addTo(mapid);

var nokia_map_glass = '/static/blog/here.com.terrain/{z}/{x}/{y}.png';

var magnifiedTiles = L.tileLayer(nokia_map_glass);

let bordercity1 = {"type":"FeatureCollection","features":
