Is there any good practice for parsing `callback_context`? I recently started working more with pattern-matching callbacks and extracting certain values from the `callback_context` became essential. Until today, I have been doing things such as

`idx = callback_context.states['packaging_concepts-div-waste_items.children'][-2]['props']['id']['index']`

😬 😬

There must be a better way! Right?!
