EngineLogging To A File

[vindicatorr]

Reason: Because the "Debug Console" buffer rolls out of view.

launch.json:

...
"engineLogging": true,
...

This, I already know.

$ ~/.vscode-insiders/extensions/ms-vscode.cpptools-1.6.0/debugAdapters/bin/OpenDebugAD7 --help
OpenDebugAD7: Visual Studio Code debug adapter bridge for using Visual Studio
debug engines in VS Code

Available command line arguments:
--trace: print the requests coming from VS Code to the console.
--trace=response: print requests and response from VS Code to the console.
--engineLogging[=filePath]: Enable logging from the debug engine. If not
    specified, the log will go to the console.
--server[=port_num] : Start the debug adapter listening for requests on the
    specified TCP/IP port instead of stdin/out. If port is not specified
    TCP 4711 will be used.
--pauseForDebugger: Pause the OpenDebugAD7.exe process at startup until a
    debugger attaches.

--engineLogging[=filePath] This is what I seek. Yet, it seems it can't be done in the launch.json file (squiggly wants boolean) and I also can't seem to run the command in the terminal but launch from vscode, hoping it'd attach/use that already running bridge.

I've seen various issues from years past where you could edit a .js/.json file for the extension and alter the args, but main.js has the args area containing --interpreter, but for vsdbg.exe which doesn't even exist.
And there is no "args" for any OpenDebugAD7 in package.json.
And https://code.visualstudio.com/docs/cpp/enable-logging-cpp doesn't even say how to set it to output to a file.
