Use WP Discourse to publish posts from Wordpress to Discourse

Hello, for some reason YouTube videos are not showing in the Discourse. So they are added in WordPress but once we publish a post and we push it to the Discourse, the video is not shown. Probably because it’s buried under the WP code?

<figure class="wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio">
<div class="wp-block-embed__wrapper">
<span class="embed-youtube" style="text-align:center; display: block;"><iframe loading="lazy" class="youtube-player" width="640" height="360" src="https://www.youtube.com/embed/IpY_IMjT9Ik?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation"></iframe></span>
</div>
</figure>

This code is from a Discourse topic created by WP.

Any ideas on how to make this work?
