display virtual keyboard when physical keyboard is pluged in

On an iPad, is it possible to display a keyboard application when a physical keyboard is connected?


- without physical keyboard, I want to be able to see my entire custom virtual keyboard (it works)

- I would like to keep only the prediction part of my custom keyboard application, when a physical keyboard is plugged in. (it doesn't work)


I haven't found a solution to realize that.


Could you please help me ?
