-If you have the AdaFruit board with built in level shifters and voltage regulator it is should work if you just plug in [https://pinout.xyz/pinout/i2c](SDA to pin 3, SCL to pin 5, VCC to pin 17 and GND to pin 20). You should then be able to find the SGP30 an address 0x58 using `i2cdetect -y 1`. If you get an error message  you probbably need to enable i2c in the kernel using [https://learn.sparkfun.com/tutorials/raspberry-pi-spi-and-i2c-tutorial](`raspi-config` and reboot)
