One problem is that display module is intended for use with an ESP8266 micro controller, not a Pi.
The good news is that it should work with a Pi if you wire it correctly.
Looking at the picture of the module and the first documentation link on that site, I can see it uses the i2c interface and works =on 3.3V. That's good. Four wires to the Pi should do it.
I can't see any numbers on the pins on the display, so...Third pin down on the right is i2c SCL. That goes to pin 5 (GPIO 3) on the Pi's header.
Fourth pin down on the right is i2c SDA. That goes to pin 3 (GPIO 2) on the Pi.
Second pin up on the right is GND. That goes to any GND pin on the Pi, like 6 or 9.
Bottom pin on the LEFT is 3v3. That goes to pin 1 on the Pi.
That's the hardware side done.
For software look for code for an SSD1306 display, which should be compatible. Width is 84, height is 48, i2c address is 0x3C.
