NO ISSUE, JUST A QUESTION: Possibility to extract widevine L1 Key after module installed

[CDRLpart]

Do you think or know if it's possible to extract the widevine L1 Key after installation of this module?
If yes, do I need a special tool or could I just use something like https://github.com/Avalonswanderer/wideXtractor , https://github.com/Avalonswanderer/widevinel3_Android_PoC
Or
https://github.com/hyugogirubato/KeyDive

Thank you, very nice project 👍
