Decrypt 802.11w (PMF) Managment packet

Hi, Does Wireshark supports decrypt (802.11) managment packets (as part of PMF connection)? If yes, there is a special way to do so? Because I have tried just to insert the keys and it doesnt work (unicast managment should use the same key as the data)

Thanks

Need Association and EAPOL packets: https://wiki.wireshark.org/HowToDecry...

Unless all four handshake packets are present for the session you're trying to decrypt, Wireshark won't be able to decrypt the traffic.

The wiki doesn't mention needing the Association Request but I find the decrypt does not work without it.
