I was trying to embed a Facebook video on my personal site but the autoplay feature is not working.

Even after following the steps from the official meta developers page for embedded videos, it's not working.

I have tried for videos from Youtube and Tiktok platform but didn't face any issue there.

Is this a Facebook limitation or something is missing that I am not doing.

Does anyone else is facing the same or the autoplay is working for them for Facebooks videos. If its working, then can someone help me with this?
