How to use the vscode-extension-telemetry.default function in vscode-extension-telemetry

export function sendTelemetryEvent(eventName: string, properties?: {
    [key: string]: string;
}, measures?: {
    [key: string]: number;
}) {
    // Check out later (no idea why default import isn't being picked up)
    try {
        reporter = reporter ? reporter : new TelemetryReporter(extensionId, extensionVersion, aiKey);
    }
    catch (ex) {
        reporter = reporter ? reporter : new TelemetryReporter.default(extensionId, extensionVersion, aiKey);

        reporter.sendTelemetryEvent.apply(reporter, arguments);
    }
    catch (ex) {

    }
}
