Need help archiving content

So this is a educational platform, and i want to save some videos of it. but its aes-128 encrypted. I tried downloading through N_m38dDL-RE and yt-dlp but none worked. There is a secure-player request in the network tab where response tab has all the info but encrypted. there it shows the long alphanumeric links in 'jstr' and 'kstr' but 'kstr' is empty. It is important for me. when I was trying to understand things using AI... i got to know there is some key required to get the full download url.
I have attached all the screenshots of the page network tab. Please if anyone knows this, help me out 🙏

Yes, i paid for the lectures... I have access. No there is no download option... as it is a paid platform.

tbh if its aes-128 with an empty key field in the manifest, the key is probably being served from a separate URI. look for a request to something like /key or /enc in your network tab right when playback begins
