Oxygen integrates with Toolset.
If Toolset is installed and fields are present for the item being edited or previewed, fields created in Toolset will integrate with Oxygen's dynamic data functionality and automatically appear in the Insert Dynamic Data dialog.
Once the Insert Dynamic Data dialog is open, click Toolset to see the available fields.
Toolset Views
To insert a Toolset View, use the Toolset View element that appears at +Add -> WordPress when Toolset is installed, or use the shortcode element.
