Diablo Port withdraw money from storage using controller

Been playing this Diablo port for some hours on my handheld and as the game stacks coins in 5k per inventory slot I decided to storage some at the Barmaid. Problem is now I can't withdraw the money because it has only a button that asks me how much I'd like to withdraw but I am not on a keyboard to type an amount... Is the any way to call a virtual keyboard or smth or any workaround for this?
