loadSound for a user uploaded file

I’m building a rhythm game in TypeScript, and I need to let the user upload a sound file, load it, and then play it on demand. I know this is possible in vanilla JS, but I want to do it “the P5 way” so my code is cleaner. Below is a minimal example of what I’m trying to do. I expected loadSound to work, but it’s not even an available method, and the p5 examples online don’t address this use case. Am I missing something, or does this have to be a feature request?

let p: p5 = myP5SketchInstance;
p.createFileInput(handleAudioFileInput);

function handleAudioFileInput(file: p5.File) {
    let p: p5 = myP5SketchInstance;
    let song = p.loadSound(file);
}

If you are wanting to use p5 then you can use the drop() method and callback the loadSound() method. Then in the success callback of the loadSound() method, play the sound …

function setup() {
  let cnv = createCanvas(400, 400);
  background(222);
  cnv.dragOver(_ => {
    background(157);
  });

  cnv.dragLeave(_ => {
    background(222);
  });

  cnv.drop(file => {
    let snd = loadSound(file.data, _ => {
      snd.play();
      p.html('playing').position(125, 100);
    });
  }, _ => {
    background(222);
  });

  let p = createP('Drag your file here ...').position(25, 100).style('font-size', '27pt');
}

Sorry, just realized you were using the createFileInput() method …

function setup() {
  ...
  createFileInput(file => {
    let snd = loadSound(file.data, _ => {
      snd.play();
    });
  });
}
