The Icon property of the EditorHandleAttribute class specifies the icon to be used for the handle sprite in the editor. This property allows you to define a custom icon that will be displayed in the scene view when the attribute is applied to a component.
To use the Icon property, assign a string value representing the path or name of the icon you wish to use. This icon will be displayed in the editor to represent the handle for the associated component.
