Technical consultation on Pebble Tracker

I’m a developer of the pebble tracker. I’ve encountered some issues related to build and flash the pebble tracker.
To be specific, the dev guide doc on the website seems being out of date, so I am confused when flashing the pebble tracker. I used Windows 10 environment.

I’ve installed the “nRF Connect for Desktop”, but the custom app “Programmer lotex(v1.4.7)” cannot be opened on it.
I noticed that there was an offical app named “Programmer”, but the app cannot recognize my pebble tracker. The error message is “not a Jlink or USB device”.
Is there any other methods to flash the “app_asigned. hex” that I have built into the pebble tracker?
