iOS PWA: how to force opening in a new window

I have a PWA saved on the home screen, this opens up standardly without search bar nor the bottom buttons (share, tabs, etc..).

So every link gets opened inside the PWA, and that is expected.

I have a problem when showing pdfs as they normally open in Safari with the "share" button and all the bottom bar, but in the PWA they open up without bottom bar and without any share button.

So my idea is to open the PDF link (http://www.mywebsite.com/download/pdf/12345) in a new safari window,.

I tried putting target="_blank" on the PDF link but this did not solve the problem.

I also tried forcing the iOS behavior by opening the app in safari with safari://http://www.mywebsite.com/download/pdf/12345 but with no luck.

How do I open a New Safari window to a link?
