[OT] Is it possible to use Wireshark to visualize RFC7268 AVP (instead of Unkown-Attribute) ?

@Rens:
In my setup, the libwireshark-data package is installed and it
contains a /usr/share/wireshark/radius/dictionary.rfc7268 file.

I will be curious if you can decode  these AVP numbered 186, 187 and 188.
Unfortunately,I couldn't find any sample over the Internet containing those AVP.
