I have a working AWS Amplify application which I deployed manually. To specify this application using the CLI, I need the so-called appId. But where can I find this? In the console, I can find the name and the appArn but not the appId.

If you have access to the AWS console and can see the App ARN field, you can find the AppId:
arn:aws:amplify:eu-west-1:xxxxxxxxxx/APPID
It has this pattern: d[a-z0-9]+
