hunk.code_window: You can access the channel your release is published under with the `releaseChannel` field in the [manifest object] (https://docs.expo.io/versions/latest/sdk/constants.html#expoconstantsmanifest).
   ## Example Workflow
   Consider a situation where you have a Staging stack for testing on Expo Client, and a Production stack for pushing through TestFlight, then promoting to the AppStore.
   On the staging stack, run `exp publish --release-channel staging`. Your test users can see the staging version of your app by specifying the channel in the query parameter of the URL (ie)`https://exp.host/@username/yourApp?release-channel=staging`, then opening the URL in their web browser, and finally scanning the QR code with the Expo client. Alternatively, they can open that URL directly on their mobile device.
