Bypass login for Nest hub (cast)

I’m trying to allow one client (google nest hub gen2) to by pass the login

I tried this but that doesn’t seems to work, I’m still asked for a login (and the nest hub don’t have a virtual keyboard)

    - type: trusted_networks
        - -- client IP / no sub
      trusted_users: !secret gcastuser
      allow_bypass_login: true
    - type: homeassistant
