Having Problems Posting for HTML5

Some context:

In my class, we are supposed to make a game on any software or engine we want. I chose Unreal Engine 4 since I have had experience with it before. And I am windows and everyone else in my class is on Mac even the teacher.

Problem:

I have made a game on Unreal Engine 4 without any issues. My teacher wants me to share it with her and 1 other person who will be my tester. I have decided to export in HTML5 format so that anyone with a link can use it. But I have tried a lot and I have only got to work on my laptop.

Question:

How do I create it so that anyone with the URL can access and play my game?
