Demo theme for Specia free

Hello, I know that the paid version of Specia offers the installation of the demo theme in one click.

But I’m looking everywhere for how to import the demo version of the theme without finding it.

I didn’t find any data-dummy.xml in the zip file of specia free.

Where can I find the demo version of the Specia theme? Even if the installation can be complicated.

Thanks in advance.
PS: sorry for my bad english, I use an online translator.
