[ISSUE] Debugging BSom (B404) using VSCode

Using VSCode on Windows 11. Had no problem doing local debug using Particle Debugger with Boron module.
Switched to B404 module and can’t start debugging session. This window pops up:
and debug console reports:

Is there any tutorial on how to debug a B40x module? The only one I’ve found is for a Boron, and that was very old…
