React-Native MC33

React Native use MC33 keyboard

Hello,

I develop an react-native android application for different Zebra Scanners and normal smartphones.
On the MC33 I have problems using the hardware keyboard of the Scanner.
Normally when I press a button multiple times the available letters from this button switch until the right one is picked.
In react-native however it always just picks the first letter.
Also I don't see a way to use the "enter" or other buttons.
Is there a way to use the typing correctly in an app without building it completely new?

Kind regards
