 The telemetry publisher sends `FeatureEvaluation` custom events to the Application Insights when a feature flag enabled with telemetry is evaluated. The custom event follows the [FeatureEvaluationEvent](https://github.com/microsoft/FeatureManagement/tree/main/Schema/FeatureEvaluationEvent) schema.
