Notifications may be unwanted for several reasons:
You can mute content in change alerts or bundle size notifications.
This is enabled by default and means you won't get alerts if a change is caused by a third-party script, such as ads, chat widgets, or analytics.
Third-parties are detected based on the domains in this list. Not all of them are muted, for example CDN content is likely to be under the website's control and should therefore trigger a notification.
You'll still get an alert if a new third-party is added.
Muting phrases allows you to mute notifications related to specific domains, URLs, console messages, or Lighthouse audits. Alerts will also be muted if the page title contains a muted word.
If a notification contains these words it will not be sent.
