thanks nostr:nprofile1qqsqa6p85dhghvx0cjpu7xrj0qgc939pd3v2ew36uttmz40qxu8f8wq8vdeta but markdown itself doesn't seem to support any syntax for an embed, it has a dodgy [](https://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE) which navigates to the video URL, not good.
I guess what you are saying is to use markdown's support for html and then use the iframe tag and hope the client doesn't strip it. Its kinda sad that it works everywhere with kind 0 but not 30023.
