NFC simple auto off (v1)

1. Automate Community
2. Security

Turns off NFC 30 seconds after it has been enabled so you don't have to.

With this flow NFC is off in general and is only made available for this brief timeframe when the user or an app enables it, which should be enough e.g. to pay with your payment app.

Displays toast messages giving a heads-up before and confirmation when turning off. Vibrates gently when turning off. No other notifications.

PLEASE NOTE: Permission "modify secure system settings" is needed to turn off NFC. Without root it can be easily enabled using ADB. Documentation on the ADB command to achieve this is provided by Automate when you enable this permission.
