That article is only valid for CYW43907, not for ST host based platforms like 1LD. You can follow the steps mentioned in OpenOCD -WICED to download and debug 1LD based custom platform (Please check the comments section as well for modifications required in jlink.cfg).
While downloading, you might need to use Zadig to change the default driver of J-Link to libusbK and while debugging you need to switch back to J-Link driver.
