Currently this feature is supported only in Whiteboards for Confluence Cloud.
Whiteboards can be embedded into Confluence pages. You can do that either with the
/whiteboard macro (see the screenshot below), or by pasting a whiteboard url onto your page.
Once you have a board embedded on the confluence page, it's important to configure which content will be visible for readers of your page.
By default the viewport will be adjusted automatically, so that all content will be visible on the page.
If you want to show a specific view on the whiteboard preview use the Custom viewport button as shown on the screenshot below.
