External SD Card Reader Adapter

Recently purchased adapter for my Macbook Air (2020) and had to additionally get a SD Card Adapter.

I am attaching SD Card Reader Adapter to the USB-C Digital AV Multi-port Adapter and using the last USB-C port on the Macbook Air for power. But the MacBook is not registering the SD Card Reader at all. I have done the normal checks to ensure that External Devices are supposed to be visible with no success. Any help would be greatly appreciated.
