1) We right-click → View frame source on the video frame
2) In the new tab that opens, press F3 and put in the search .mp4
3) Find the last one in the search and select the link that starts from this ending and is in ""
4) Paste the link in a new tab and press the three dots at the bottom right and select download.
If it doesn't work, then we do the same procedure for the immediately preceding link.
The reason for not showing the video with optional download is because the video resolution of the link must be equal to or less than the one that uploaded it.
