Curly brackets with iPad with Apple Magic Keyboard

Hello, I'm using the app to connect from my iPad to my MacBook. I use it for coding, but I can't type the curly brackets. I tried all the combinations of the "Macro" and "Ignore Left Alt" switches in the app settings, but nothing changes. The keyboard layout is Italian in both the iPad keyboard and the Mac keyboard.

The key combination to type the curly brackets is "shift + option + è" for "{" and "shift + option + +" for "}".

Thanks
