(example url : [The Best 7 Alarm Clock Apps of 2023](https://www.lifewire.com/best-alarm-clock-apps-4766942) )

1. Run the APP and set the alarm time.
2. Press the Home button and the smartphone goes to the ‘background’ state.
3. Use other APPs.
4. I want to make an alarm sound in ‘10 minutes later’ (at the set alarm time)

This is a question about that matter.  
Q1) How can I create an event (notification) after a set time in ‘background’?

- In summary, **I’m curious about how to make it work in the ‘background’.**
