Load Local Image using phaser js

I’m downloading some code from Rosebud AI, and when I start with their link or an external link, it works. However, when I try to use my own local storage to play the assets, it’s not working.

    this.load.audio("buttonSound", "assets/Button.mp3");
    this.load.audio("backgroundMusic", "assets/bg.mp3");
    this.load.audio("stoneDropSound", "assets/StoneDrop.mp3");
