Agreed with David. If you don’t use it already, download the “Smart Pianist” app onto your tablet or phone and get a USB-B cable (piano end) to USB-A or USB-C with a USB to lightning converter if needed. The app is well worth it (it’s free anyway) to control the piano and has some other cool fonctionality like traking chords from songs in your iTunes library on the device, or showing the sheet music from the 50 demo songs built-in the piano. Good luck!
