App Insights TelemetryClient - Migrating from V2 to V3

Question

We have been using the App Insights V2 TelemetryClient to create custom events in our Spring Boot Java app. We are trying to migrate to V3. Although the following web site says "There are typically no code changes when upgrading to 3.x.", in our case, the existing code gets a compile error, because the TelemetryConfiguration class no longer exists in V3.

https://learn.microsoft.com/en-us/azure/azure-monitor/app/java-standalone-upgrade-from-2x

    TelemetryConfiguration.getActive().instrumentationKey = metricPublisherRequestDTO.ikey
    val telemetryClient = TelemetryClient()

    telemetryClient.trackEvent(
        metricPublisherRequestDTO.name,
        metricPublisherRequestDTO.properties,
        metricPublisherRequestDTO.metrics
    )

We need to be able to programmatically set the instrumentation key / connection string, because this is a generic service that we use to talk to any App Insights instance. We can find no way to do that. I tried the following, but it doesn't work:

    val telemetryClient = TelemetryClient()
    val telemetryContext = telemetryClient.context
    telemetryContext.connectionString = metricPublisherRequestDTO.ikey

Does anyone have any idea what we need to do this?
