How to use Figma?

Problem/Motivation

I tried adding https://www.figma.com/design/aADVsc8fdsENnUaKePvVpg/Experience-Builder-D... but I got error The given URL does not match any known oEmbed providers.

Same if I copy that document to my drafts (so that I have full rights) and then I click "Share" and "Copy link".

This seems a bug but since I'm no familiar with Figma..
