Trouble connecting the waveshare OLED 128x128 module

Hello guys, i am new to coding and trying to connect components to arduino. I am currently struggling with connecting the waveshare OLED 128x128 module to an arduino uno and nano. This is where i bought the screen: https://www.robotics.org.za/W13992?search=oled%201.5"%3B=. These are the specs of the module:

Wave OLED 1.5 inch 128 X 128 Module

This is a general OLED display Module, 1.5inch diagonal, 128x128 pixels, 16-bit grey level, with embedded controller, communicating via SPI or I2C interface.

Quick Spec

  • Driver: SSD1327
  • Interface: SPI / I2C
  • Display color: White
  • Grey level: 16-bit
  • Resolution: 128x128 (most other competitive products are typically 128x64)
  • Viewing angle: >160°
  • Operating voltage: 3.3V / 5V
  • Dimension: 44.5 x 37 (mm)
  • 128x128 high resolution
  • 16-bit grey level, better display effect
  • Supports SPI or I2C interface, configured via onboard resistor
  • Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)

i have tried to follow the steps shared by Waveshare, however the screen is not working. I have tried to look up youtube videos and tried to follow their steps but nothing seems to work. This is the link to the waveshare democode which i followed: https://www.waveshare.com/wiki/File:1.5inch_OLED_Moudle.7z.

I have installed the SSD1327 and U8G3Lib. Please help, maybe i am missing something.
