Thank you for the Type To Siri macro!
I had to change the string for the process name to work with my German MacOS installation. I am sure this is needed for other non-US installations too.
After replacing the following in all Script blocks it worked fine for me:
- tell process "Notification Center" -> tell process "Mitteilungszentrale"
The strings for the description of the notifyWindow and for the textField don't need to be localised.
