STM32_Programmer_CLI.exe doesn't give result about the process.

My goal is to use the STM32_Programmer_CLI.exe from an application, but, for the moment, I just write down command lines in the Command Prompt (cmd.exe).
However, the commands of writting the flash ( -w yourbinfile.bin )and erasing it completely (-e all) does not return any kinf of results. I just delivers a "STM32CubeProgrammer v2.21.0" response. Why?
