Hi, I started using a Macbook Air like 2-3 days ago and I am now trying different browsers (Orion one of them). My device is using macOS Monterey 12.4. I needed the notification feature for a few websites but it still doesn't seem to work right now, which is kinda a dealbreaker. Although, it definitely feels faster than Safari when I used it.
I used the following website for testing: https://www.bennish.net/web-notifications.html
It didn't work on Orion, but when I tried it on Safari and Brave, it worked.
