fcm token is valid after PWA(home screen app) is uninstalled

Hi,

I'm testing ios push on PWA, but I can't have the way how to detect whether the PWA is uninstalled or not.

After uninstalling app and deleting all caches of safari, fcm token is still valid. It returns 'success' even after a few days.

testing devices: iphone 13 (ios 16 developer beta), iphone se2 (ios 17 beta)

Thanks in advance.
