I'm using your web messenger SDK in headless mode to build a custom UI. I've added to support for enabling co-browse support. When a co-browse session begins, the agent has the ability to draw on the user's screen but there doesn't seem to be any way of erasing or hiding the drawing without ending the co-browse session.
When using your own out-of-the-box widget, the drawing seems to fade out and disappear after a few seconds. I don't see anything in your CobrowseService plugin docs that would suggest a way to enable that same behavior with a custom UI. Am I missing something? Is there any other way of erasing the agent's drawing? Or at least is there a way to prevent the agent from drawing?
