Title Order shipped with body Your order is on its way and permission granted gives a format-checked payload.

This builds and format-checks a payload only. It does not send a push notification to any device, and it cannot reach other browsers.

Will this send a notification to my phone?

No. It only builds the payload text and checks its format in this browser.

What does the permission field mean?

It records what this browser reports. If it says denied, notifications stay blocked until the browser setting changes.
