Embedding a Mailchimp signup form into a topic

I’d swear I did this once before… might have been years ago, for a different hosted-Discourse instance. ¯\_(ツ)_/¯ I have this vague recollection that someone on the Discourse team threw together a Component that injected the needed j/s . . . I’d like to drop this into a topic, but it doesn’t work (of course) because of the inline j/s:

<!-- Begin Mailchimp Signup Form -->
<link href="//cdn-images.mailchimp.com/embedcode/classic-071822.css" rel="stylesheet" type="text/css">
<style type="text/css">
	#mc_embed_signup{background:#fff; clear:left; font:14px Helvetica,Arial,sans-serif;  width:400px;}
	/* Add your own Mailchimp form style overrides in your site stylesheet or in this style block.
	   We recommend moving this block and the preceding CSS link to the HEAD of your HTML file. */
<div id="mc_embed_signup">
    <form action="https://umbrellacast.us16.list-manage.com/subscribe/post?u=171541754ab434ecfc0d61e17&amp;id=ab9a3173ca&amp;f_id=00656ae0f0" method="post" id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate" target="_blank" novalidate>
        <div id="mc_embed_signup_scroll">

<!--End mc_embed_signup-->

i think maybe you can use Typeform support to do this.

…what’s “Typeform” and how would I use that with populating a Mailchimp audience?

…but isn’t it [what is discussed in the first topic you linked to] simply a onebox in Discourse? Do users stay on the Discourse topic? …or does clicking it take them off to a Typeform?

…there was a way [which I’ve lost/forgotten] to directly embed the Mailchimp signup form into a topic.
