You can click on the Xstore Studio Library button: https://postimg.cc/t1Mpm1LN and then you will be able to see and import all the available designs only on that page of your site: https://postimg.cc/wtZYQCmW https://postimg.cc/w7g82c1d
Other than these designs and sections are not available to import, for now, you can submit a request here: https://www.8theme.com/taskboard/
OR you can install the theme on a local test site and copy the section or design manually from there to your live site as per your requirements.
