i2c0 = I2C(0, scl=Pin(54), sda=Pin(53), freq=100000)
env3 = ENVUnit(i2c=i2c0, type=3)

The configuration that i used to communicate with it was these:

M5.Ex_I2C.begin(); // Initialize I2C for MS5637 with SDA=GPIO53, SCL=GPIO54
Wire.begin(M5.Ex_I2C.getSDA(), M5.Ex_I2C.getSCL()); // Reconfigure default Wire to use M5.Ex_I2C pins
barometricSensor.begin(Wire);

I'm not even sure if everything is needed but it works.
