Hey Patrice!
Thanks for reaching out.
At this time, unfortunately the closest thing to this “out-of-the-box” with the plugins is to use the Ticket Settings section of Event Tickets Plus to add tickets to various post types.
Here’s a screenshot of the option where you can do this:

This will make it so that you can add tickets to those post types. If you add tickets, then the ticket form will show up at the bottom of the content.
I hope this helps โย let me know if it does! There is unfortunately not a shortcode or similar option at this time ๐
Thank you,
George
