Accessing field within non-public subclass using reflection?

[SpectralGerbil]

Hiya, to make a long story start I am altering the Phantom AI and part of this involved using reflection to fetch various private parts of the AI system (like the various goal objects in Forge). Problem I'm having is, after I run all these calculations, I need to put them back into the AI goal - but I can't quite do this.

See, the field I'm trying to edit is "attackTargeting", within the Phantom.PhantomAttackPlayerTargetGoal subclass. Problem is, this subclass is not public. Attempting to use reflection to get the value of the field simply throws me an error that the field and subclass are not visible. I'm experienced in Java but have absolutely no idea how to get around accessing a non-visible field without being able to edit said field (which I can't, because it's vanilla code). What can I do here?

There is a bot on forge's discord where you can lookup the runtime field and method names.

I've already been using the bot, but thank you for the link! Had no idea of this functionality!
