This was discussed at the contributors meetup, cf the notes:
Pierre indicated Brian Smith and Adolfo were already looking into the issue. A conversation ensued about who is currently maintaining the front end app communication, with Maria suggesting that Adolfo is temporarily maintaining it, until eduNext takes over. Jorge offered to reach out to Adolfo for more on this, as Pierre observed that this micro frontend is mandatory for Palm and this issue could be significant for different languages.
@arbrandes You seem to be already on this, is that correct? Any blocker?
