`investigations.questions.answer`

Answer a question with its id, one of its optionId answers (or none_of_these when the person settled it by hand), an optional note of up to 1000 characters and an idempotencyKey. An offered answer does only what Oatmilk wrote down when it asked (confirm or decline a hold, put a receipt on a hotel's charge or take it off, link a transaction to a trip); none_of_these only closes the question. Every answer is audited, and a question closes once answered. Contributors can answer only questions about transactions they own.
