/**
 * Provides information about the [KMLLayer](https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-KMLLayer.html) from which a graphic originates.
 * Also provides access to the [KMLSublayer](https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-support-KMLSublayer.html) that contains the graphic.
 * The [origin](https://developers.arcgis.com/javascript/latest/api-reference/esri-Graphic.html#origin) information may be available when a graphic is returned from methods such as
 * [hitTest()](https://developers.arcgis.com/javascript/latest/api-reference/esri-views-MapView.html#hitTest).
 *
 * @since 5.0
 * @example
 * // get a point from view's click event
 *  view.on("click", async (event) => {
 *    // Search for all features only on included layer at the clicked location
 *    const response = await view.hitTest(event, {include: layer});
 *    // if graphics are returned from layer, get the layer id from graphic origin
 *    if (response.results.length > 0) {
 *      const originId = response.results[0].graphic?.origin?.layer?.id;
 *    }
