Error place box comments facebook

Hello, I’m trying to put a box comments facebook with this code amp:

Header:
?? <script async src = “https://cdn.ampproject.org/v0.js”&gt; </ script>
<script async custom-element = “amp-facebook-comments” src = “https://cdn.ampproject.org/v0/amp-facebook-comments-0.1.js”&gt; </ script>

Coment.php

<amp-facebook-comments width=”486″
height=”657″
layout=”responsive”
data-href=”https://www.directlyrics.com/adele-25-complete-album-lyrics-news.html”&gt;
</amp-facebook-comments>

The problem is that it eliminates or does not appear the code in the <amp-facebook-comments page …. it seems that it will be automatically deleted

I would like to know if your Amp plugin eliminates these tags or what is happening, thanks
