Setting Retention in Sentry on premise on kubernetes

I am setting up On-premise Sentry on Kubernetes. I am wondering how to set the retention period.
I am using a Kubernetes Cronjob to run the Sentry docker with argument “cleanup”. I know that the default value is 30 days. However, I am not sure how to configure it to something else.
Could someone share their knowledge on this?


On the deployment the cron trigger starts.
