Step by step

Open Notifications
Open Settings and tap Notifications.
Done
Tap App notifications
App notifications is at the top: Change notification settings for each app.
Done
Find the app
Every app has a switch. Turn it off to stop all its notifications, or tap the app's name for more choices. We tapped Chrome.
Done
Turn off Allow notifications
The app's page starts with Allow notifications. Below are Sound and vibration, where notifications show (Lock screen, App icon badge, Notification pop-up), Notification pop-up style and Show or hide content when locked.
Done

If you do not see this option

No notification categories? Google says that if an app has categories, you can tap one for more options. For Chrome, our page had none; at the bottom was Configure in Chrome, which we did not open. Source: Control notifications on Android
App switch already off? In our list DB Navigator was off and marked Deep sleeping. Turn the switch on to allow it again.

If this does not work

Still getting notifications from a website? Those come from Chrome. Configure in Chrome, at the bottom of Chrome's page, leads to Chrome's own settings; we did not open it.
Want them quieter, not off? Leave Allow notifications on and switch off Sound and vibration, or untick Notification pop-up.
Missed one you turned off? Notification history keeps a list: see notification history.

About this guide

You can silence one noisy app and keep the rest. One UI 9 lists every app with its own switch.

The screenshots are from our Samsung Galaxy A57 with One UI 9 and Android 17 (build A576BXXU6BZIE), in Dark mode. We only looked and changed nothing. We used Chrome.
