Looking for GraphicsLayer post remove event

GregoryBologna

I am adding buffer graphics to 2D MapView and would like to have an event on the add\remove to check for errors. The "on" event below doesn't report an event.

const bufferLayer = new GraphicsLayer({
  title: 'some-bufferLayer',
});
	
let geometry = sketchGeometry; // a polygon

const bufferGeometry = geometryEngine.geodesicBuffer(
	geometry,     // geometry, The buffer input geometry
	buffer_size,  // distance, The specified distance(s) for buffering
	unitType,     // unit, Measurement unit of the distance
	false         // unionResults, Default Value: false
);

if (bufferLayer.graphics?.length === 0) {
	bufferLayer.add(
		new Graphic({
			geometry: bufferGeometry,
			symbol: sketchViewModel.polygonSymbol,
		})
	);

} else {
	
	bufferLayer.remove(bufferGeometry);
	bufferLayer.graphics.getItemAt(0).geometry = bufferGeometry;
}
view.map.add(bufferLayer);

// ???
// No event happening here.
bufferLayer.graphics.on("after-remove", function(event){
});‍‍‍‍‍‍‍

This worked equally as well in that example

      const polygonGraphic = new Graphic({
        geometry: polygon,
        symbol: fillSymbol
      });

      const bufferLayer = new GraphicsLayer({
        title: 'some-bufferLayer',
      });
      view.map.add(bufferLayer);

      bufferLayer.graphics.on("after-add", () => { console.log("Added"); });

      bufferLayer.add(polygonGraphic);

      setTimeout(() => {
        bufferLayer.graphics.on("after-remove", () => { console.log("Removed"); });
        bufferLayer.graphics.removeAll();
      }, 2000);
