Apponitments+ where to find shortcode?

Hello!

I'm trying to test out the appointments+ plugin but can't get it to work.

Where do i find the short codes?

if i go to display and "create an appointment page" and click the checkbox and click save changes nothing happens exept that the checkbox gets unchecked.

I read through the guides and watch the videos but they all have a shotrcode tab but i don't have one.

How do i get this to work?
