The [documentation](https://docs.arduino.cc/tutorials/uno-r4-wifi/qwiic/) states that the following statement must be included to support the use of the second I2C interface (for Qwiic): ``` Wire1.begin(); libraryName.begin( Wire1 ); ``` Unfortunately, there is no reference on how to include the access to **libraryName** in the sketch. Currently, compilation fails. Thanks.
