In the tutorial Android GBoard Morse Code Control with Circuit Playground Express, Adafruit demonstrates using the HID Keyboard functions to enter data into an Android phone and then use a feature of the Google GBoard keyboard to turn Morse Code into text.

But you don't have to use Morse Code, you can plug the CPX right into your Android phone or tablet and have it type just the same way it does on your computer with a spreadsheet above. This time you can go mobile. All you need is a special USB cable called OTG (on the go).
