How to cut out vector patterns in inkscape?

Question

Vector editor

Downloaded vector patterns from freepik .
I want to use the luxury pattern as the background - image of the site. However, I did not work with vector graphics and I do not know how to get these patterns from a file.
I downloaded inkscape and opened the .eps file that was in the archive. I don't know what to do next.
Tell me how to get patterns from a file.
