but when I try to get this video element using Axios request I am not getting

axios.get('https://www.instagram.com/reel/CYd4S2Wrbtg/').then(html => {
   console.log(html.data, 'r+++++++++++++++') 
   res.send(html.data);
});

I think the video element is not in the source of the page. What I mean to say is the video element is created using javascript after the body is mounted, which means when you hit a get request you get a basic HTML file with loads of javascript which renders the video later. So in a way, the video element doesn't exist when you hit a get request.
