--sudo flag not doing anything with cnspec scan ssh

[tas50]

Describe the bug
I'm trying to scan a Linux host over ssh and that requires using Sudo to elevate my privs. I assumed I should just add the --sudo flag to my scan ssh command, but it's not working and not producing any errors either.

To Reproduce
Steps to reproduce the behavior:

1. cnspec scan ssh SOME_HOST_IP --incognito --sudo

Expected behavior
Either an error that passwordless sudo is not enabled or a prompt for the sudo password.

Desktop (please complete the following information):

• OS: macOS
