Raspberry Pico I2C and LCD library

Hello everybody,
I want to connect a 2x16 LCD with I2C on the Raspberry Pico (with Earle F. Philhower port ) that is on a Raspberry Pi Pico teaching board V2 board. What are the required libraries and how do I set the GP4 and GP5 pins, ie I2C0 / SDA and SCL respectively? Obviously I use a 3.3V / 5V translator. I only know how to use this display together with Arduino Uno.
