Help needed with resetting HP1920 48G (JG927A)

Hello - We have an HP 1920 48G that we forgot the password to, so we need to clear the password or do a factory reset as a next best option.  Does anyone know how to do either of these on this switch?  On other HP switches I've been able to do this with the "clear" and "reset" buttons, but I can't find either of these on this switch.  Thank you for any help.

"Password Recovery capability is enabled. To perform this operation, first disable the password recovery capability using the undo password-recovery enable command in CLI"

Now?

Solved, skipping current configuration allows access to the switch without authentication.
