You can do it as mentioned here if you are using capacitor: https://capacitorjs.com/docs/apis/background-task

import { Plugins } from '@capacitor/core';

const { App, BackgroundTask } = Plugins;

App.addListener('appStateChange', (state) => {

  if (!state.isActive) {
    // The app has become inactive. We should check if we have some work left to do, and, if so,
    // execute a background task that will allow us to finish that work before the OS
    // suspends or terminates our app:

    let taskId = BackgroundTask.beforeExit(async () => {
      // In this function We might finish an upload, let a network request
      // finish, persist some data, or perform some other task

      // play your sound

    });
  }
})

However, this will risk the app being terminated, and being labeled as impacting battery life as you won't finish the task.

The best option is to have a Backend service that will send push notifications every 10 minutes. In this way, OS will handle the notification instead of the app in the background.
