Angular: How go to have multiple PWA app under same domain

Question

I am facing a big problem since last one week.

I am working with Angular app which have one feature like create Business Card with url dedicated. Example is given below.

mysite.com (main site)

mysite.com/card1 (card1)

mysite.com/card2 (card2)

So how to have pwa for each of this card seperately.

1. I don't think this would require code i did
2. I know this can be achieved by having multiple service workers.

Above 2 points i know. Please help me with this. I had searched a lot about this but I didn't find anything specific for Angular.
