Hi team, I will need technical guidance for my scenario which I am facing right now. I have created a k8s cluster and deployed signoz in it, and override the default value of signoz helm chart service type to LoadBalancer so that I can use signoz endpoint to post telemetry data to the cluster. My applications are not running on Signoz cluster as I have a dedicated cluster only to run signoz. I am using the grpc endpoint to export data with this value http://20.244.78.20:4317. My queries are - 1. How this endpoint operates on http despite serving to endpoint using grpc protocol? 2. How can I securely export telemetry data using the above endpoint?
