Description of your issue, suggested solution and other information

Explanation of your issue in arbitrary form goes here. Please make sure the description is worded well enough to be understood. Provide as much context and examples as possible.
If work on your issue requires account credentials please provide them or explain how one can obtain them.

Downloading private videos using credentials does not work. It appears that any facebook video that has /video/ in the url doesn't work when using user credentials, even public videos. The same public video that won't work when using credentials will work when you don't supply credentials. If the private video is shared, and you use the shared post link to try and download the video (/posts/), while using credentials, the video downloads. Example:

Public video: https://www.facebook.com/severeweatherEU/videos/2292036711019417/
Downloading without credentials works. Downloading with credentials fails. If you find someone who has shared this video, take their share link and try to download that with credentials, it downloads fine.

Here are two outputs. The first one is me trying to download the public video with credentials:

The second one is me trying to download the video through somebody's public share link:
