Embedding video from Facebook

*CMS 3.7.1

Does anyone know how to embed videos from Facebook straight into a page in the Silverstripe CMS?

I am using the Insert Media (tree icon) button in the editor and pasting a Facebook video URL. It does embed but it has a lot of space below the embedded media when I preview the page. Do Facebook videos work as inserted media or are there workarounds?
I am a content editor, not a dev, and increasingly I find relevant videos to embed that are only hosted on Facebook, rather than Youtube or Vimeo.

When I inspect the element in my page preview here is the code I get:

<div class="media leftAlone"><div id="fb-root" class=" fb_reset"><div style="position: absolute; top: -10000px; height: 0px; width: 0px;"><div><iframe name="fb_xdm_frame_https" frameborder="0" allowtransparency="true" allowfullscreen="true" scrolling="no" allow="encrypted-media" id="fb_xdm_frame_https" aria-hidden="true" title="Facebook Cross Domain Communication Frame" tabindex="-1" src="https://staticxx.facebook.com/connect/xd_arbiter/r/afATJJjxKE6.js?version=43#channel=f37e1a125a77d4c&amp;origin=https%3A%2F%2Fnzta.govt.nz" style="border: none;" data-gtm-yt-inspected-1321092_9="true" data-gtm-yt-inspected-1321092_10="true" data-gtm-yt-inspected-1321092_11="true"></iframe></div></div><div style="position: absolute; top: -10000px; height: 0px; width: 0px;"><div></div></div></div>
