}, AnyHashable("gcm.message_id"): 1633432922216200, AnyHashable("categoryId"): , AnyHashable("google.c.a.e"): 1, AnyHashable("notification_category"): , AnyHashable("state_id"): 6131e95a02008ceb91df7f1f, AnyHashable("message"): Kledn Company - hi, AnyHashable("$state"): chat, AnyHashable("badge"): 22, AnyHashable("title"): Chat, AnyHashable("chat_type"): 1, AnyHashable("google.c.fid"): euTqw93Ln0HTny5NGFgUha, AnyHashable("category"): Chat, AnyHashable("google.c.sender.id"): 93576622797, AnyHashable("sound"): default.caf]

Start by reproducing the firebase_messaging notification case on iOS 15 with the app in the foreground, then compare it with iOS 14 and background behavior using the APNs payload shown. Done means the default notification sound plays reliably for foreground notifications on iOS 15.
