Greetings Everyone, Kindly I want to ask few questions: 1- Is there a way to create/register the first admin user of signoz (first time login from UI) using signoz helm chart ? 2- Is there a way to import signoz dashboards from helm chart. 3- Is there a way to modify the retention period for metrics, logs and traces from helm chart ? We are trying to automate these things in order to deploy on multiple clusters. Thanks in advance 🙏
