Embed support for Facebook Watch

I'm both YouTube and Facebook content creator, I started to become a content creator at Facebook because Facebook has a YouTube alternative, Facebook Watch and it's on Facebook's ecosystem. I'm advertising my Facebook Watch content on my Discord Server for people who don't have Facebook yet and check my videos exclusively to Facebook Watch

the embed don't show up unless I put the longer one but it still not showing up the video on the embed but I still could see the video on Facebook Watch

(which is still kinda dumb, all videos in Facebook Watch are driven by all Facebook Pages only and on Facebook Page if you post a video, you can't make it private or unlisted, only public unlike YouTube), on YouTube, it stays fine as I expected, this should have on Facebook Watch links too (even only for shortened links)
