As far as I'm aware, any MacOS app at all can be notarized. It's like adding a digital signature - it doesn't matter what's in the app or what it's made of, it's just adding a (cryptographic) "verified" stamp.
Well, notarization is not that simple. That's why I was asking here if anyone has already succeeded in notarizing a Construct app.
Even codesigning an app created by Construct is everything but easy. It took me a lot of time and researches to finally do it.
