Weld for yourself.

USB uses a TYPE-C connector.

After welding is completed, you need to download the firmware. Use another downloader to download the firmware: STLinkV2.J28.M18_firmware. After downloading the firmware, use STM32 Programmer to upgrade the firmware. When entering the upgrade interface, it will prompt that the STLink cannot be found, and you need to replug and unplug the USB.
