The default behavior of the GtkAssistant is to switch to the page after the current page, unless the current page is the last one.

A handler for the ::apply signal should carry out the actions for which the wizard has collected data. If the action takes a long time to complete, you might consider putting a page of type AssistantPageType.PROGRESS after the confirmation page and handle this operation within the Gtk.Assistant::prepare signal of the progress page.
