JetEngine Post Expiration Period Addon GPL Overview:

The Post expiration period add-on allows you to display a new post for a limited time. You also could set an expiration action so that a post would be deleted or changes the status to draft after the date elapses. This feature works if you have limited-time offers for the customers on your site or want clients to publish posts, which would be deleted, like, after a month. The expiration period can be added via the WordPress JetEngine form and set in the Insert/Update Post notification settings.
