The latest Chrome Canary build for Android offers new settings for notifications allowing you to set importance for notifications requests to two new options: “Low” and “Trivial”. As a result, website notifications will appear silently to you without making any noises.
We already knew Google’s efforts about make things quieter on notifications front via previously released experimental flag but the new options for notifications are now available to users irrespective of whether the flag enabled or not
hrome on Android now makes Website Notification Prompts less annoying
Chrome and Chromium Edge can now silence the Website Notification Prompts
To see the new notifications settings in action do the following
1. In the latest version of Chrome Canary, click on menu icon > Settings > Notifications
2. General > Permission requests
3. Click on Importance and choose one from the options below.
High: Make sound and pop on screen
Default: Make sound
Low: Show silently
Trivial: Show silently and minimize.
Considering how annoying notification prompts often are, imagine the Low and Trivial options should be a quiet welcome addition for users.

As of now, there are two Permission requests entries in Settings. We’re not really sure about Google’s intention behind this; Its likely-just a bit of code that needs polishing. Ensure you set Permission Requests’ importance as low or trivial for both entries to make sure they work properly. You can follow this feature’s development here.
Of course, we already knew about Mozilla’s desire to solve notification spam by blocking website notifications by default on the desktop from Firefox 72 onwards when there is no interaction from the user. Google’s changes are just a different take on tackling the same problem.
