Does .create() with same token return same promise?

can i do someHook.create({token}) and then in another nested function (where the hook is not in scope), do someHook.create({token}) again, and then await it, and it be the same hook/promise? i'm uncertain about what .create does under the hood, and if creating with the same token goes to the same promise as i'd expect, or not.

nice, this makes sense. can hooks be sent down to step functions? i would think "no", right?

is there a way to strip unserializable stuff before facing an error? i have an array of "events" and hooks might be a prop in there, and the full array is passed down - i'd prefer to have the unserializable stuff stripped other than getting a runtime error
