License location on hard drive (Rhino 5)

Hi guys, I have a rather old Rhino 5.5.5 version on my old Mac (used to play around with it a couple of years ago).
On there, I have a commercial license which, I think, was a license key code.

Unfortunately, I can’t find the key code anymore.
Does Rhino save the license locally after I validated it?

ChatGPT told me, I should look at Library/Application Support/McNeel/Rhinoceros/License Manager/Licenses, however, I have nothing there.

Do you have an idea?
Thanks in advance!

(system specs: MacOS Monterey, 12.0.1)

Hi Frederick -

The “license”, yes, but not the key code. For licensing issues, please contact sales@mcneel.com directly.

Alright, thanks for the quick response!
