Other than the official documentation and related SFSE questions indicate the Error reporting of Second Generation Managed Packages (2GP) seems to behave differently that with 1GP.
I want to make this tool work with 2GP Managed Packages: https://github.com/rsoesemann/lma-app-cockpit but couldn't get a 2GP Managed Package that was created using the errornotificationusername
parameter to send notification emails on Unhandled Apex Errors.
Is this supposed to work or did I discover a bug?
