This bit was a made a little bit more frustrating as latest Azure App Insights/Monitoring SDK (Open Telemetry) didn't support logging to the required customEvents table - so I've had to fall back to the legacy AppInsights SDK which is a bit annoying.

I got bitten by polyfills in Angular the other day, they polyfill the global dispatchEvent event with their own shim which doesn't support CustomEvents!

The native EventTarget is a hidden gem, but its TypeScript support is a bit of a "black box". I’ve put together a small wrapper to get a 100% type-safe event bus with zero runtime overhead.
