Change default orange color of the circle that helps in changing shape of Sketch

[SanatSathyan]

Hi,

I am trying to implement the Esri Sketch and I would like to know if there is a way to actually change the color and size of the small orange symbol, which is used to update the shape of the drawn sketch. I have gone through the documentation as well as various community posts and there are ways to update the symbols as well as the selection outline, but couldn't actually find a way to update this [attached ref image below]

Any solution or suggestion on how to achieve this would be really helpful.

Thanks.
