Unable to get mp3 file as require function of node.js.

We are creating a sound effect playback app with Expo (React Native).

I'm trying to make it by referring to the Expo official document, but here, I'm importing the mp3 file as a require function.

Code for the Expo official document. (https://docs.expo.io/versions/latest/sdk/audio/)

const soundObject = new Audio.Sound();
try {
  await soundObject.loadAsync(require('./assets/sounds/hello.mp3'));
  await soundObject.playAsync();
  // // Your sound is playing!
} } catch (error) {
}

It's my code.

var testPng = require('./assets/test.png')
var testMp3 = require('./assets/test.mp3')
console.log(testPng)
console.log(testMp3)

Unable to resolve "./assets/test.mp3" from "App.js"

undefined Unable to resolve module ./assets/test.mp3 from App.js:
