Hello! I've built a web app using Genie + Stipple and I would like to deploy it to

I have grav setup with nginx and letsencrypt, so it’s accessible via ports 80 and 443 (I have only a tenuous grasp of what that means btw). The main thing I was wondering was how to convert:

route("/", ui)
up(8000, open_browser=true)

To what you should do on a web server. Do I replace it with up(443) ? How do I “link” the app within my website?

EDIT: linked to the wrong grav website.
