* `workbook:variables:update`

Outbound events:

* `url:onchange`

## Workbook features

### Sigma documentation in embed elements

Embed [Sigma documentation](https://help.sigmacomputing.com/) pages in workbooks (using the embed UI element) or any other applications that support iframe content.

For more information, see [Embed element](https://help.sigmacomputing.com/docs/intro-to-ui-elements#embed-element).
