Is the appointment of the NBU Deputy Governor legal?

I read the news that Volodymyr Lepushynskyi was appointed Deputy Governor of the National Bank, and he will be responsible for monetary stability. I became curious—was this appointment made in accordance with the law? Can the Council of the National Bank independently appoint deputy governors, and are there any special requirements or restrictions for such positions, for example, regarding experience or education? I would like to understand if all legal procedures have been followed.
