I have the following code and need to autoplay my video in my website. but it doesnt autoplay, nor it loops the video with no control.

```
<div style="position: fixed; z-index: -99; width: 100%; height: 100%">
    <iframe width="100%" height="100%" src="https://www.youtube.com/embed/3fRxOjkik0g?autoplay=1&loop=1&showinfo=0&controls=0" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
</div>

```
