how to load mp3 sound in phaser3?

I got following error in visual code when compile.
ERROR in ./src/assets/switchSound.mp3 1:3
Module parse failed: Unexpected character ‘:diamonds:’ (1:3)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See Concepts | webpack
(Source code omitted for this binary file)

:wave:

You need to use file-loader (webpack 4) or asset modules (webpack 5).

Thanq I solved…
