Thank you. Is there a way to pass multiple installer URLs in that mode?
Running wingetcreate update Sidero.talosctl --version 1.9.0 -t <token> --interactive only prompts me for one installer URL and if I select edit manifest files and then Installer File > Installers, it errors out with:

System.NullReferenceException: Object reference not set to an instance of an object.
