Connect Heltec ESP32 wifi lora to External TFT ili9341

I am trying to connect the ESP32 wifi Lora to a generic tft display.
I dont understand which pins i should use to connect the device to the external TFT.
Has anyone been able to achieve this?
If so, can you please share how you got it to work, i.e which pins you connected and example code you used.
Many thanks.
