Footer Scroll-to-Top PHP

I accidentily deleted the code for the WP Scroll to Top that goes in the footer theme editor. Please, can someone just write it back down for me? It doesn’t matter what the settings are, I just need the call to action. This is what I have so far:

<div id=”footer-2″ class=”pt-3 pb-3″>
<div class=”copyright container”>
<?php if( get_theme_mod( ‘marketing_agency_footer_scroll’,true) != ” || get_theme_mod( ‘marketing_agency_resp_scroll_top_hide_show’,true) != ”) { ?>
<?php $marketing_agency_theme_lay = get_theme_mod( ‘marketing_agency_scroll_top_alignment’,’Right’);
if($marketing_agency_theme_lay == ‘Left’){ ?>
<i class=”fas fa-long-arrow-alt-up p-3 rounded-circle”></i><span class=”screen-reader-text”><?php esc_html_e( ‘Scroll Up’, ‘marketing-agency’ ); ?></span>
<?php }else if($marketing_agency_theme_lay == ‘Center’){ ?>
<i class=”fas fa-long-arrow-alt-up p-3 rounded-circle”></i><span class=”screen-reader-text”><?php esc_html_e( ‘Scroll Up’, ‘marketing-agency’ ); ?></span>
<?php }else{ ?>
<i class=”fas fa-long-arrow-alt-up p-3 rounded-circle”></i><span class=”screen-reader-text”><?php esc_html_e( ‘Scroll Up’, ‘marketing-agency’ ); ?></span>
<?php }?>
<?php }?>
<div id=”wpfront-scroll-top-container” style=”opacity: 0.5; right: 20px; bottom: 20px; display: block;”>

<style=”opacity: 0.5; right: 20px; bottom: 20px; display: block;”>
</style>
</div>
