Demo Importer function not showing

Hello HB support team,

I’ve been following the official installation and demo import Youtube video and uploaded the Highend theme zip file, but a few clicks away, I cannot see Demo Importer tab under Highend Theme option page – what should I do to get my site set up like those demo pages? Do I need to upload one zip with everything that downloaded from my cart to be able to see demo effects?
