Have you tried casting Siri Harry Potter/ Wizarding World spell on your iphone with Siri yet? It's fun. Here are the some:
To turn on your torch: "Hey Siri, Lumos"
To turn off your torch: "Hey Siri, Nox"
To open an app: "Hey Siri, Accio (app name)"
I'm not sure if there are more I didn't get past turning my torch on and off.
