Can’t create pages with ulisting

Hi, I am new to uListing. So maybe I am a little bit stupid.
I have installed demo data and because they are making some settings in wordpress that seemed wrong to me, I have delegated all demo data incl. attributes and so on and began from scratch with uListing.

Now I stuck by creating pages for wordpress. Such as Home, search page, etc. How do I create pages with the wanted layout.
I knew that I have to modify views in listingtypes. But than?

There are no Gutenberg Blocks. There are no Elementor widgets.

May be you could give me an overview how uListing works in that way? How could I set a starting page if I can define one?

Confused ??
