I have an AWS amplify React Native App. For setting up, I am required to run

amplify pull
It asks certain question. As my backend and frontend repository are separated, particularly for option "Do you plan on modifying this backend?", I select "n" while working on React Native app. Now, I am setting up CI/CD with MS Visual Studio App Center. For each development, I need to set up an automated way to give these values. I have tried setting up custom "appcenter-pre-build.sh"

#!/usr/bin/env bash

npm install -g @aws-amplify/cli
#Git Link: https://github.com/aws-amplify/amplify-cli/issues/2140

AMPLIFY="{\
\"appId\":\"<app id>\"\
\"envName\":\"<env name>\"\
\"defaultEditor\":\"vscode\"\
\"noUpdateBackend\":\"true\"\
\"configLevel\":\"general\",\
\"useProfile\":true,\
\"profileName\":\"default\"\
}"

amplify pull  --amplify ${AMPLIFY} --yes

For simplification, I tried the command from terminal as well
amplify pull --appId <appid> --envName <env name> --yes --noUpdateBackend true

My specific questions are

1. I do not want to update backend. How can I set up this option for AppCenter CI/CD? I found this code, but it will not work as it is not mapped to any CLI arguments.
2. How can I bypass the browser authentication for getting the client id?

The closest resource I found is this. It will be great if someone can help me out here. I am checking out this as well.

I think this might help me. Resolving the issue for now. I will reopen if it persists.

I tried the script mentioned in Headless Amplify Pull. Authentication bypassing is resolved. But entire backend code is still getting copied. From the code, it seems, script should be sending 'No' to the question "Do you plan on modifying this backend?". But entire backend code is still getting pulled.

Is there anyway to customise it? I do not want to modify the backend in my React Native project.

Closing it in the favour of #5275. There is a PR going on. Hope to see the feature in live soon.
