Need help with key

[Angel_Cyclops]

As a noob, Ive been trying to understand how key retrieval works, which is the crux of my quest.

Ive been going through various threads including Dumping L3 from android studio and others but without much success.

So I managed to find an encrypted dash link, its KID(3 KIDs - a default, one for video and one for audio), pssh, lic(vdocipher) etc, but Im unable to get the key. I thought the session id would be it, but that doesnt seem to be the case. But as I led with the word noob, its also highly likely Im making a mistake in the syntax or even the punctuations. Anybody with a little time on their hands that can help me understand what Im doing wrong?
