BME688 breakout not being recognized

I went to this website provided by pimorini:

I copied the code:

from breakout_bme68x import BreakoutBME68X
from pimoroni_i2c import PimoroniI2C

PINS_BREAKOUT_GARDEN = {"sda": 4, "scl": 5}
PINS_PICO_EXPLORER = {"sda": 20, "scl": 21}

i2c = PimoroniI2C(**PINS_PICO_EXPLORER)
bme = BreakoutBME68X(i2c)

Pasted it into thonny and run the code with the tufty2040 connected via usb and the sensor attached to it. I was expecting a tuple however I simply get the error mentioned before.

From what your saying are my pins wrong. If so what are the correct pins?
