Amp ads + Regular ads within content through functions in paired mode

Hi,
I recently installed wp Astra theme which is amp supported and activate the paired mode in AMP. Previously I’ve two Adsense units on my single pages – one below the title and one within content after 2 paragraphs. I added the following code in single-layout.php

<?php astra_single_header_after(); ?>

<div class=”entry-content clear” itemprop=”text”>
<?php if ( function_exists( ‘is_amp_endpoint’ ) && is_amp_endpoint() ) : ?><amp-ad
layout=”fixed-height”
height=100
type=”adsense”
data-ad-client=”ca-pub-5367747358451280″
data-ad-slot=”1919115743″>
</amp-ad><?php else : ?><div class=”top-ad”><style>
.gas_below_title { width: 320px; height: 100px; }
@media(min-width: 500px) { .gas_below_title { width: 435px; height: 300px; } }
@media(min-width: 800px) { .gas_below_title { width: 728px; height: 90px; } }
</style>
<script async src=”//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js”></script>
<!– GetAndroidStuff Below Title –>
<ins class=”adsbygoogle gas_below_title”
style=”display:inline-block”
data-ad-client=”ca-pub-5367747358451280″
data-ad-slot=”2618604399″>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script></div><?php endif; ?>
<?php astra_entry_content_before(); ?>

Which perfectly work on both regular and amp version. However, for the second ad unit, I used to add the following code in functions.php. Now I can’t figure out how to implement the amp version of adesnes code within the following code in functions.php. Please help within the following code

//Insert ads after the second paragraph of single post content.

add_filter( ‘the_content’, ‘prefix_insert_post_ads’ );

function prefix_insert_post_ads( $content ) {

$ad_code = ‘<div class=”td-g-rec td-g-rec-id-content_inline”><script async src=”//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js”></script>
<ins class=”adsbygoogle”
style=”display:block; text-align:center;”
data-ad-format=”fluid”
data-ad-layout=”in-article”
data-ad-client=”ca-pub-5367747358451280″
data-ad-slot=”5639820018″>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script></div>’;

if ( is_single() && ! is_admin() ) {
return prefix_insert_after_paragraph( $ad_code, 2, $content );
}

return $content;
}

// Parent Function that makes the magic happen

function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
$closing_p = ‘</p>’;
$paragraphs = explode( $closing_p, $content );
foreach ($paragraphs as $index => $paragraph) {

if ( trim( $paragraph ) ) {
$paragraphs[$index] .= $closing_p;
}

if ( $paragraph_id == $index + 1 ) {
$paragraphs[$index] .= $insertion;
}
}

return implode( ”, $paragraphs );
}
