You can use Oxygen with any WordPress plugin. In general, they will behave just as they do when using them with a normal WordPress theme.
Some plugins generate output that you would like to insert into your page. You may display this output using a Shortcode, Widget, or Code Block.

Shortcodes are commonly used to embed contact forms, event calendars, elaborate sliders, pricing grids, and more.
