dev container - python debuger installation - extension name

[flegare]

I'm trying to avoid manually install the debugger on each build (dev container), what is the correct extension handle to use? Right now tried this without much success:

       [...]
	"customizations": {
      // Configure properties specific to VS Code.
		"vscode": {
        // Add the IDs of extensions you want installed when the container is created.
		"extensions": [
			"ms-vscode.python-debug".    <---- This sadly don't work
		]
		}
	},
	[...]
