Before, during consent initiation, fintech provided account as a list of IBAN strings. Now we need to provide account list as a list of account reference type:

Before: "accounts": ["DE80760700240271232400"], "balances": ["DE80760700240271232400"], "transactions": ["DE80760700240271232400"]

Now: "accounts": [ { "iban": "DE80760700240271232400", "currency": "EUR" } ], "balances": [ { "iban": "DE80760700240271232400", "currency": "EUR" } ], "transactions": [ { "iban": "DE80760700240271232400", "currency": "EUR" } ]
