Thats what pissed me off, the URL looked not appealing to me.
I managed to get started, my URL seems to be victorious-blouse. https://victorious-blouse.glitch.me/test.html
It seems to me that glitch creates them randomly.
I guess it requires some $ to get that changed.
Weather I get facebook to work is a different story.
For the moment app.js works as expected.
