Is there any way to override a single layer for the legend widget? I'm using JS API v4.0 and have one 3D polygon extruded layer, which doesn't show up in the legend (unlike my other non-3D layers). Was curious if there is a way to "override" the legend in this case - specify a different renderer for this layer that is only used in the legend (while the 3D extruded polygon symbol and associated renderer is what's used on the actual map?
Any suggestions for a workaround here?
