Add buttons in Picture in Picture

I am making a music visualiser with picture in picture functionality.

    const canvas = document.createElement('canvas');
    const ctx = canvas.getContext('2d', { alpha: false });
    const img = document.getElementById("playing-img")
    const video = document.createElement('video');

    canvas.width = canvas.height = 200;
    ctx.drawImage(img, 0, 0, canvas.width, canvas.height)
    video.srcObject = canvas.captureStream();
    video.requestPictureInPicture();

But i can't figured out if i can add button like skip or previous.

Did someone know how to add buttons in picture in picture window?
