Has anyone set up ArchiSteam farm on truenas scale correctly?

I saw that truenas scale has Archi, but once I downloaded it, I was pretty much stuck at the point where I need verification.

I used my app to approve the sign in, but nothing happened further. From YouTube videos I need to run some command file to say that I approved sign in. Don't know how to get that open on true nas though.

What can I do?
