Downloaded environment from the market place but I cant open the project

I have downloaded “American Style Diner Interior” from the marketplace. In my vault I am getting an option to add to project. If I create a new project and add it I just see all the assets materials etc in the browser.

I want to see the assembled scene with lighting without having to assign all the materials myself. How can I do this?

It it supposed to be a whole environment with lighting and a simple exterior.

Thanks. R

Open the Map with the Scene?
