I don't know if that's a violation sorry. Regarding adding it
upstream. I don't think so. At least judging by the activity of the
maintainer. See here:
https://github.com/SebastienWae/app-launcher/issues

There are open issues starting a year ago and the author hasn't replied
to any of them. But I could try my luck and contact them to add the
copyright notices.
