Allow user to start drawing on Whiteboard without signing in (as can be done on Surface Hub)
We want to use Whiteboard on collaboration boards we have installed into conference rooms. These boards are intended to provide functionality similar to the Surface Hub. Many users balk at using them because of the requirement to sign in before being able to start drawing. There should be a capability to allow the same experience in Whiteboard as is provided on the Surface Hub, so users can draw before signing in, and only need to sign in when the drawing needs to be saved.
