Even when specifying these I2C ports in line 48 of DFRobot_GR10_30.cpp: _pWire->begin(22,20); the board fails to initialize, presumably because the ESP32 can't find it on the I2C bus.
All works fine on an Arduino MKR WiFi 1010 whose I2C pins default to SDA=11, SCL=12
How can I define the I2C pins?

I plan to use glass in the front, will there be any problems with recognition?

Solved. It was a wiring problem. The sensor and its library work just fine.
