Configuring QuiverBow's Arms Assistant

I am trying to make the Arms Assistant from the QuiverBow Mod ignore my PortalGun Sentry turret. However I don’t know what to put in the writable book, the documentation is not very extensive…

Here is what I tried:

• craft Book and Quill
• write “Sentry Turret” in it
• give it to the Arms assistant
• give a weapon to Arms assistant

Result: it attacks the sentries.

What am I doing wrong here? I tried also “PortalTurret”, which is the name of the Sentry turret item (I think not of the entity), but that didn’t work either.

I would appreciate an answer that is general enough that it allows me and other people to apply it to any kind of entity that needs to be blacklisted.
