identify

Question

I use identify to identify feature when click on map: import * as identify from "@arcgis/core/rest/identify.js"; view.on("click", (event: ViewClickEvent) => {     const params = new IdentifyParameters({                   geometry: event.mapPoint                   // .....             });
      identify.identify(url, params);}); Is it possible to know a feature that is already identified, so that identify.identify won't be called when clicked on it again?

When I click on it again, I want show it's popup.

Thanks.

I got a solution: use hitTest

view.on("click", (event: ViewClickEvent) => {     view.hitTest(event).then(({ results }) => {          if (results.length == 0) {               const params = new IdentifyParameters({                   geometry: event.mapPoint                   // .....             });
              identify.identify(url, params);           }        });});
