I can't make stm32_programmer_cli work. Please help?

[CHand.3]

The program can't find any ST-Link connections:

But I can use the STM32CubeProgrammer to flash my board via ST-Link/V2 SWD.

Could you please help me to figure out what is missing?

I need to write a program to flash the board and I can't even see it! Please help.

Thank you.

The ST-LINK is using the SWD interface, the "USB" connectivity is looking for STM32 directly connect via USB, either in Boot Loader mode, or with DFU Device Firmware.

STM32_Programmer_CLI -c port=swd

OMG... Of course!!!

I did not know that parameter. I need to improve my skills by looking for information in the manuals. Thank you very much.
