How to remove a Cesium event listener after use Angular?-CodePudding

I have a function that adds a Cesium event listener in a subscription. I would like to know how to remove it after use.

Here is my code :

this.layerService.visibilityChange.subscribe((layer){
    viwer.scene.globe.tileLoadProgressEvent.addEventListener((count) => {
        console.log(count);
        if(viewer.scene.globe.tilesLoaded){
            viewer.imageryLayers.pickImageryLayerFeatures(ray, scene);
        }
    })
})

After executing this code, the event is still console.log the count each times tiles are loaded. How can i remove it juste after the pickImageryLayerFeatures() has executed ?

In fact I have read the doc eheh, And Cesium tell us that tileLoadProgressEvent return a function that will remove this event listener when invoked.

Just like addEventListener you can also remove event listner.

viwer.scene.globe.tileLoadProgressEvent.removeEventListener(myFunction);
