Using Communication Components > Whiteboard component

Whiteboard component

This component lets you create and edit text, boxes, and lines in a real-time shared environment. To create a shape, you select a tool and click on the whiteboard area; you can also drag the shape to a new position or edit the text. When you press the Delete key, all actively selected items are deleted.

The Whiteboard component does not require scripting if you use it with the SimpleConnect component.
