[embed]Using WordPress 5.5.1 there is no embed option after the video is uploaded

I have looked at many posts explaining how to embed a video mp4 from my computer to WordPress and they invariably show a box with the option to embed the video. In my WordPress version 5.5.1 this never shows. All I am left with is a link which when clicked downloads the video in extreme bottom left of screen withe the necessity to click "Open" or "Open when finished". Why am I not seeing the option to embed?
