Make sure Do Not Disturb is toggled off: Notification Center > Notifications (Scroll to the top)
βOpen Notification Center > Notifications > gear button in the lower-right corner of Notification Center (https://support.apple.com/en-us/HT204079)
In the Notification Settings, click on Google Chrome (Badges, Sounds, Banners)
And toggle on "Allow Notification from Google Chrome".
Repeat steps 3 and 4 but this time find your PWA in the app list instead of Google Chrome.
Update your Mac to the latest software version available.
