In Skype for Business 2015, is it necessary to set up an Office Web Apps server to use a Whiteboard in order to draw and share the drawing over a chat? (I am referring to the feature below)

Or is an OWA server necessary only when you want to share PowerPoint slides? (I am referring to the feature below)
