Is there currently any way to modify the color of the orange selection outline in the ArcGIS 4.x Sketch tool?
See the basic Sketch sample here: https://developers.arcgis.com/javascript/latest/sample-code/sketch-geometries/. Notice when dropping a point on the map, or selecting an existing point, an orange outline surrounds the point you are editing. Inspection into the ES Modules (@arcgis/core/widgets/Sketch/SketchViewModel.js) shows that this orange outline is defined as a symbol on a clone of the user's placed graphic, and that clone is placed into an internal graphics layer defined by the sketch view.
I have tried to find and manipulate this internal layer by iterating through my MapView's .allLayerViews, but this method has shown to be very hacky (and I cannot get the symbology to render correctly on creation of a graphic, only on update).
Thanks in advance for any help that can be offered!
