Hello mariosmic,
I think this is a Google issue, rather than a GRAPHISOFT one.
I gave it a try, and it won't recognise these Standard App Links as hyperlinks for me either (Google Docs and Google Sheets), but from Chrome, and Safari in general, it works for me (eg. if you click the link in your post here from Chrome, it should work for you too). I even tried in Microsoft Word and Excel on iOS, and they work fine there too.
I think we just have to accept it doesn't work in Google Docs/Sheets, or contact their support for help.
