PWA Button Integration into Knack App

I’ve done some research on integrating a PWA integration popup for Knack applications, but without much success.

If the subject hasn’t already been raised elsewhere, I’d like to know if you’ve already managed to make a popup of this type appear, and if so, what’s the method?

Thanks !

As I recall, you can create a PWA style of button on the home page, but as soon as you go to login assuming your security is set to cookies, it breaks out of the PWA and into a browser page.
