We have an android app that we want to retrieve reports for , programatically from google play console.

For the purpose in Google Cloud Console we created a project to which we created** a Service Account** and invited it to Google Play Console as user.

Google Analytics API
Analytics Reporting API
Google Cloud API

All enabled. But probraatically we are still unable to fethc data for the statistics reports.
We have created the api key for the service account , .json file and and all other data necesarry is provided to the developer.

We have copied to Cloud Storage Path URI from Google PLay console -> Download Reports – > Statistics for the Installs report.

But the request is returning that there are no buckets. Buckets Array is empty .
So do we need to buy Storage in Google Cloud Console and create a Bucket ?
If we create a Bucket how to assign it to the Google Play Console reports ?
The

gs://pubsite_prod_123456789/stats/installs/

is for example the Cloud Storage Path URI in Google Play . So if there is already a link for that bucket can we just enable the option to fetch from it or to assign it to a project in Google Cloud Console.
