2. https://app.videas.fr/v/7dde6333-0506-4d95-a2d7-312d4188a5af/

Currently, we could only download single video and playlist is not available right now due to they are for private hosting only, by link or somewhere else.

### Provide a description that is worded well enough to be understood

We could not download the link: https://app.videas.fr/embed/7dde6333-0506-4d95-a2d7-312d4188a5af/, due to missing videas.fr.py or app.videas.fr.py in extractors under yt_dlp directory. 

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
