Hi, how do I modify Hello Neighbor?

Hello. How do I modify Hello Neighbor. I have installed epic games launcher and unreal engine, but when I launch unreal engine, it hops straight in to the creating mode and no the main site or whatever. So i do not even get a chance of downloading the hello neighbor mod kit. I would really appreciate if someone would help me.

I don’t think this place it where to ask how to modify a game.
