Architecture for Web and PWA

I am writing a system that will primarily be used on the web. People will login, interact with content and connect with each other. This is very straight forward and I am clear on how to do this.

I am considering adding a Progressive Web App (PWA) to the system. I would want the PWA to run in its own area and be a Vue app.

Basically both a full web app, and a minimal but relevant PWA.

How do I run both of these systems side by side?
