Documentation issues

Anyone know how to take the Encryption Keys to decrypt packet in wireshark using the dissector ? I try all in my knowledge but I'm not having success.

My scenario: I have a Matter plug, and i use the chip-tool to connect with it. Everything work right, but my goal is create the IM for wireshark. And my problem is being able to find the decryption key.

Thank you very much for everyone who will help me in this work.

I am digging into the same question, the current progress is reading the code and try to print the key into the log.

For your reference, https://community.silabs.com/s/question/0D58Y0000AhNKGeSQO/how-to-print-the-network-key-of-matter?language=en_US

Let me know if you found anything.
