How to use the n8n-core.UserSettings.getUserN8nFolderCustomExtensionPath function in n8n-core

	if (options.watch === true) {
		buildCommand += ' --watch';
	}

	let buildProcess: ChildProcess;
	try {
		buildProcess = spawn('node', buildCommand.split(' '), { windowsVerbatimArguments: true, cwd: process.cwd() });

		// Forward the output of the child process to the main one
		// that the user can see what is happening
		buildProcess.stdout.pipe(process.stdout);
		buildProcess.stderr.pipe(process.stderr);

		// Get all the installed packages which contain n8n nodes
