@vishnu-srinivas You should show much more info (type, picture, link) about your OLED module to get any really useful help.

0.96" I2C 128X64 OLED module with 4 pin header
You should simple connect OLED pins to Omega2(+) pins: GND to GND, VCC/VDD to 3.3V, SCL to SCL and SDA to SDA if you had a module with I2C interface. I2C level shifting is not necessary at all. -
0.96" I2C / SPI / ... 128X64 OLED module with more than 4 pin header
Probably it's a module with 3 or 4 wire SPI interface by default so you should "convert" it to I2C and connect also some additional header pins (RES, DC, ...) correctly. Maybe the PCB has some info or the seller provided some description for you.
