Pull ups on i2c devices - noob question

So i have this simple OLED screen i used in my esp32 project. I heard you need pull up resistors on the SDA and SCL pins, however when I was devolping this on the breadboard, it was working without them. Do i need to include them on my schematic for PCB? Does the PCB the OLED moduel is on contain these resistors already? Was planning to just solder the thru whole compenet to my board - as is
