DevilutionX Diablo 1 How to withdraw money from storage using controller?

Been playing this Diablo port for some hours on my handheld (Emuelec 4.8) and as the game stacks coins in 5k per inventory slot I decided to store 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?
