Firmware to read USB flash drive using CH376S and STM32

I need a firmware for the STM32G031 to communicate with the CH376S (through UART) and read a text file located on a USB flash drive connected to the CH376S (through USB connector). This should be easy if familiar with the CH376S. Ideally you would have a CH376S and STM32 of your own to test with, but we can test on our side if needed. This is the first stage of a bigger project so this could lead to more work.
