const askPermissionToApplyUpdate = async (

) => {
  Alert.alert(
    "An app update is available",
    "May we restart the app to apply the update?",
    [
      {
        text: "No",
        style: "cancel",
      },
      {
        text: "Yes",
        onPress: async () => {
          await applyUpdateAndRestart()
        },
      },
    ],
  )
}

const App = () => {
  useAppLifecycle({
    onLaunch: () =>
      simpleExpoUpdate({ whenPresent: "applyUpdate" }),
    onFocus: () =>
      simpleExpoUpdate({ whenPresent: askPermissionToApplyUpdate }),
  })
  return <></>
}

"applyUpdate" applies the update immediately, restarting the app.

You can also pass a function to whenPresent which accepts an argument that's an async function that you can run to apply the update on your own terms.
