Intersect two featureLayers in arcgis api js

Hi,

I have two featureLayers (RegionsLayer and CommunesLayer) so my goal is to get only the communes under a given Region (spatial query), actually I can get a specific region with definitionExpression

 const featureLayerRegion = new FeatureLayer({
                    url: "https://xxxxxxxxxxx/arcgis/rest/services/TEST_SPATIAL/MapServer/3",
                    outFields: ["*"],
                    definitionExpression: "ID_Reg = 1",
                    popupTemplate: templateRegion
                });
 map.add(featureLayerRegion);

and now I want to get all the communes from CommuneLayer that belong to this region ?

@benchikh ,

Here's the link to the API reference which shows the intersecting of 2 feature layers using geometry engine:
