Real-time queue stats via Statistics API in C# SDK

I need to pull live queue observation data like waiting count and available agents for our custom C# desktop app. I am using the Genesys Cloud .NET SDK. I tried calling the Statistics API, but the documentation is sparse on real-time endpoints. The historical queries work fine, but I need the current state. I tried constructing a request to /api/v2/analytics/queues/realtime, but it throws a 404 Not Found. Is there a specific endpoint or method in the SDK for real-time queue metrics? I need this for a screen pop that shows agent availability before transfer.
