Connect shell mineOS plugin in truenas scale

Hello everyone,
I am reaching out regarding a small issue.
I have truenas scale 22, and I installed the MineOS app, I was able to access the portal, create servers, everything is working fine.
I wanted to access the shell of my different servers, I can do it from the truenas shell, but it’s not very convenient. I wanted to use putty, but when I connect with the app id, I get “Access denied”. I tried with my root access, but I can’t access the app directly.
Would you have any idea on how to proceed?
Thank you for your help.
