I've tried to add the following TelemetryInitializer:
public class HiddenIpsTelemetryInitializer : ITelemetryInitializer
public void Initialize(ITelemetry telemetry)
telemetry.Context.Properties["Client IP address"] = "Hidden";
But it doesn't do what I want. It adds a new property to "Custom Data" section, and what I want is to hide the "Client IP address" in "Request Properties" section.
