How to eliminate Native android Keyboard textbox

when a project with a text box is launched on android, when you bring up the keyboard, there is a white box above the keyboard with the text you type. I am building an educational typing game, so this is taking up space, very distracting, and makes no sense to be in a typing game.

also the keyboard i am particularly trying to help people learn is called DOTKey, an a-typical keyboard, so building that keyboard inside of unreal is unrealistic for my scope.

any information on how to access this would be wonderful! i assume it is unreal that is bringing up the white text-box, because they keyboard in other apps (like messaging) don’t have it
