Some of the telemetry is not added until when later when VSCode get bundled with it and some proprietary stuff and signed for distribution. This is where VSCodium do the stuff. they take the same source code, apply some patches and build the program with open-vsx open source marketplace and they call it a day.

All of this actually happens and piped using github action found on the repository. You can have a look there.
