It always bears repeating, push notifications are not private, neither for Android, GrapheneOS, nor iOS, even if you use end-to-end encryption. If you are privacy conscious, you should either use settings to hide sensitive data from push notifications or turn them off altogether.
If you turn off notification history on Android, should be enough to avoid such "attacks". Hiding sensitive content inside notifications only hides it in the lock screen. If your OS keeps a clear log of them, it's useless.
Edit: didn't know Signal actually has settings to hide their own notifications. I was thinking about Android's "hide sensitive content" setting.
I'm actually talking about sensitive data on Google/Apple hosted servers, as well as on the phone itself!
