shortcode buttons are missing and container width

Hi support team, I like the theme Inovado so far and I am about to discover all the features.
In the documentation I found that Inovado comes with shortcodes – but they are not shown in the dashboard menue (in the pages setup)

Can you tell what it needs to make them show?

Also, I want to use the boxed layout and would like to know how I can make the container smaller. How can I manage this?

Sincerely
suzi
