Technically it probably belongs to the TransactionWithdrawal, but
logically it belongs to the withdrawal flow. So I added it there for now.

Hmm but how do you i18n that Uri? Also, if we want wallet-core library
provide strings for the UI, it needs to know the current locale. Maybe
better to cover all cases in the API and let the wallet UI take care of
displaying text to the user?
