Magic SMS Button with OLED screen

Hi! We are using your instructibles for the Magic SMS button, but we would also like to add a Adafruit 3045 Assembled FeatherWing OLED - 128x32 OLED Add-on for Feather so that not only a phone number is notified when the button is pressed, but also a message appears on the OLED screen. We were wondering if anyone could give us some guidance on how to make this happen? We have been working with Cricuitpython, so have some familiarity with that, but by far not experts. The general plan was to have the button on one breadboard and the feather and featherwing on a different breadboard and have them connected together. We also need to provide battery power to the entire system. Any help, or guidance would be greatly appreciated.
