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

I have tried to download teachable course lectures using this command `yt-dlp -f hd_mp4-720p --cookies cookies.txt --verbose -N 32 -o "./f/%(chapter_number)s-%(chapter)s/%(autonumber)03d-%(title)s.%(ext)s" https://www.xx.com/courses/1046245` but I am getting this error `ERROR: No suitable extractor (Teachable) found for URL teachable:`

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
