As explained in What Makes a Good Notification, good notifications are timely, relevant, and precise. If your page asks for permission to send notifications on page load, those notifications may not be relevant to your users or precise to their needs. A better user experience is to offer to send users a specific type of notification, and to present the permissions request after they opt-in.
Under URLs, Lighthouse reports the line and column numbers where your code is requesting permission to send notifications. Remove these calls, and tie the requests to user gestures instead.
If notification permissions was already granted or denied to a page before Lighthouse's audit, Lighthouse cannot determine if the page requests notification permissions on page load. Reset the permissions and run Lighthouse again. See Change website permissions for more help.
code contains calls to
notification.requestPermission(), and notification
permission was not already granted, then notification permission was requested.
