If you are using Catalina, Click on Copy Link worked best for me.
Execute the following curl command. Replace the PASTE HERE portion below with the contents from Copy Link. Change your-file-name.mp4 to whatever you like.
curl 'PASTE HERE' --output your-file-name.mp4
If you are using Big Sur, Click on Copy as cURL worked fine for me.
Paste your link and append --output your-file-name.mp4
