How to connect to i2c devices behind Qwiic Pro Micro USB-C controller

Qwiic System

I have a raspberry pi 3b with three sensors attached (sds011, sgp30, scd30). The sds011 is connected via usb to raspberry pi, but the other two sensors are i2c devices and they are connected via gpio pins (diff i2c addresses). This all works fine but I wanted to get rid of gpio connections, so I bought the Qwiic Pro Micro USB controller to attach i2c devices via USB.

I have it all hooked up but cannot figure out how to connect to Qwiic Pro Micro USB controller in python and access two i2c devices behind controller in python. I currently connect to i2c devices in the following manner.

        i2c = busio.I2C(board.SCL, board.SDA, frequency=50000)
        scd = adafruit_scd30.SCD30(i2c)

        i2c = busio.I2C(board.SCL, board.SDA, frequency=100000)
        sgp30 = adafruit_sgp30.Adafruit_SGP30(i2c)

So what is the magic incantation to connect to i2c devices via Qwiic Pro Micro USB controller in python on raspberry pi. image of setup below. Any help would be appreciated. Thanks!

I think you just need to name/declare the 2 buses different; for example i2ca i2cb

The examples I gave was when connecting to i2c devices directly with no Qwiic Pro Micro in between. I assumed that I had to connect to Qwiic Pro Micro in order to get to i2c devices. The i2cdetect does not see any i2c devices when connected via Qwiic Pro Micro, so not sure how I can connect directly to either i2c sensor. Also, the i2c devices are on the same bus with different addresses (0x61, 0x58). Does this make sense?
