Get JSON value based on the value in a sub-node - json

Question

The following JSON payload is attached to the Webhook when someone submits a form.
{
"event_id": "01G9HND6HYK185YMA9Z5CZ3BV0",
"event_type": "form_response",

}
}
]
}
}
The answers are inside the node form_response.answers. As we see, there are three answers posted, each with a somewhat different structure based on the type of question. To collect the correct value, I should first look at the field.id to know which question this answer corresponds to.
E.g. If field.id = "AfpCiPiAmHjD" then I know I should pick up the value 42 from its parent node.
What value should I write in a Power Automate flow to fetch this value using a Variable step?
