Push notifications from PWAs are another area that is unnecessarily limited on iOS. They only work if the user has added your PWA to their home screen and Safari doesn't support the install prompts available in Chrome and similar.
So your users will need to go out of their way to add the PWA to their home screen and then they can receive silent push notifications because Apple says sound and vibrations are only allowed for native apps.
