  ### Currencies (Optional)
  In the `Cost Overview` panel, users can choose from a dropdown of currencies to see costs in, such as Engineers or USD. Currencies must be defined as keys on the `currencies` field. A user-friendly label and unit are **required**. If not set, the `defaultCurrencies` in `currency.ts` will be used.
