Question can i use unity essential assets in a kickstarter campaign trailer?

I understand that the store's assets are not allowed for videos, since their license only applies to interactive media, but I don't know if I can't use the essential unity assets either, which I think they mention serving for demonstration purposes.
I certainly plan on making the characters, but I hope it won't be necessary to also make all the props that I'll be using in the background during the video.
Thanks in advance
PD: sorry for my bad English
