Now I have an existing backend amw like this :

I want to integrate it to my new android project , how can i achive it ?
I am currently following this guide (https://docs.amplify.aws/lib/project-setup/use-existing-resources/q/platform/android) , add amplifyconfiguration.json but not working :
And then I tried to run command like this : https://github.com/aws-amplify/amplify-cli/issues/5006
amplify pull --appId <correct Amplify App id> --envName <env name>
but still not sure where to find the appId .
