Cannot see HoloLens2 system keyboard display pad

Hello, I am building an app with MRTK in Unity and I am deploying it to the HoloLens 2. I am calling the system keyboard TouchScreenKeyboard, but it is not showing the display pad part of the keyboard, i.e., when I am entering the characters with the system keyboard inside the app, I cannot see what I am typing. I'm using the default keyboard.
