You just put in withdrawal swift payment details including account currency, swift code, account number, account name (first party only transfers) and country of your account etc. Not done any withdrawals yet however.
It does not show any fees or mention any in app. Maybe I need to actually go through process to see them or maybe they just take the FX. Perhaps someone else whose done it can answer this question.
