Getting the Published date for a Confluence Page?

I need to show, and sort by, the date a page is published on a Confluence wiki.

For a new page that’s published immediately it’s the created date. However if the page is set to publish in the future it’s not, and the history.lastUpdated.when date is right.

Until the page is edited, when that changes to be the edit date.

Is the publish date accessible via the REST v1, REST v2 or GraphQL API?
