Can't setup onlykey

I just got an OnlyKey and tried to set it up. I run Ubuntu 22.04 and installed the app. Whenever I run the app I get:

Your OnlyKey is locked
Please enter your PIN

I don’t have a PIN. What should I do?

Is it possible that you held down the #3 button for 5+ seconds? If so it set a PIN with quick setup OnlyKey User's Guide | Docs

The way to reset your OnlyKey to factory defaults is to enter 10 incorrect pins.
