Amazon SNS Client and Dev Services

[akil-rails]

I am following the getting started guide here. I am using the dev services support mentioned here.
I write a script to create the SNS topic, specifying the script location with quarkus.aws.devservices.localstack.init-scripts-folder.
The starter code however, requires the topicArn to publish an SNS message, and I am wondering how to get the topicARN (since the script runs in the container, how do I set the TOPIC_ARN for the app that runs on my local?)
