Transferring money to a Croatian account?

Hi,
I’m travelling in Croatia right now, and need to pay my rent. Now I know Revolut transfers to any bank are free in theory, but the app won’t let me select HRK (Croatian Kuna) as the currency. If I transfer GBP (or some other currency), will there be any charges anywhere?

Thanks,
Alex
