How to test incoming notifications when the app is not in the foreground (not supported in Expo Go)

1. SDK Version: 45
2. Platforms(Android/iOS/web/all): iOS and Android

My question regards testing / handling incoming notifications when the app is not in the foreground (not supported in Expo Go)

Based on this doc it says not supported in Expo Go (Notifications - Expo Documentation)

I believe the work around was to create a custom adhoc build of Expo Go to test notifications when Expo Go is not in the foreground.

But the docs on building a custom build (see link above) note that this is not allowed in SDK >=41.

I am using SDK 45.

How can I test notifications when Expo Go is in background when I can’t use a custom adhoc build of Expo Go?
