How do i add buttons to the cyd basic version

Bit of a newbie here i got one nrf module with a antenna a esp32 wroom and a 2.8 inch touchscreen display without the touchscreen chip (was scammed and didnt even know so i was troubleshooting it thinking i didnt do something correctly) but basically how do i add buttons and can i even do it? I was googling it and searching for 3 hours and every answer was either its impossible or straight up didnt work? or if there is a bruce version that works on the 0.96 oled display that could work too.
