This plugin adds a script file in head section without Async or defer, which currently slows down the site by delaying FCP.

<script id="zest-main-script" src="https://cdn.zestpush.com/frontend/686972616bc6321b4ece-80cf48fff0.js"></script>

Expected:
<script id="zest-main-script" src="https://cdn.zestpush.com/frontend/686972616bc6321b4ece-80cf48fff0.js" defer></script>

If Dev’s can add defer loading support, it would be a great performance improvement.
