Loading ESP32-C3 AT Bin on Xiao ESP C3 board

I want to flash the ESP32-C3 AT Bin firmware using the flash_download_tool_3.93 to extend the AT command set to the XAIO ESP32-C3 accesed via the USB and a serial terminal.

On the Espressif download page, the link to ESP32-C3 AT Bin is unavailable. Has anyone loaded an AT command set on the XAIO board?
