Send message to allies/enemies after technology researched

Anyone have any idea how i can do this? Or should I just give it up because it’s impossible at the moment? I thought of a message like when Atheism or Cuman Mercenaries was researched. I could not find such an option in the AGE. Will this be possible in the near future?

Do you need it to be a mod file? You can do this with triggers

I want apply in data mod, not in scenario trigger. I suppose this can’t be used as a data method yet. However, i would like to see some new features implemented that are currently hardcoded. Maybe I’ll make a topic in the near future where I’ll list several other options that could be easily edited in the near future.
