Vividly Theme, st-list-videos - where to setup?

i bought the vividly theme for wordpress yesterday. I tryed the demo page and there is a widget called st-list-videos, that i can use when i create a page with elementor. But i can not find any place, where to tell that widget, what to display… i cant even change the demo data…

I hope you can understand me, my english is not so good.
