iOS push notification settings

I’m using iOS 14 on an iPhone 12 and Brave version 1.22.1 (20.12.10.23)

(1) I’m getting banner push notifications from either Brave rewards or Brave browser (I didn’t get a chance to take a screenshot when it appeared). I think it had something to do with Brave rewards and crypto. I’d like to turn off all notifications, whether from Brave rewards or the browser.

(2) Under Settings > Notifications, in the alphabetical list of apps, there is no Brave browser. So I have no way to toggle the push notifications on/off on iOS.

(3) I’ve checked and there is this help thread for a similar issue on Android, but not yet for iOS: How to stop push notifications.
