I need to get root folder id and filter folders which have root folder as their parent folder. Using Nodejs and google drive API v3 . This is my code and how I change this code to get root folderId?

const service = google.drive('v3');
			service.files.list({
			auth: client2,
			fields: 'nextPageToken, files(id, name, webContentLink, webViewLink, mimeType, parents)'
		  	}, (err, res) => {
			if (err) {
			  console.error('The API returned an error.');
			  throw err;
			}
			const files = res.data.files;
			if (files.length === 0) {
			  console.log('No files found.');
			} else {
				
			  console.log('Files Found!');
			  for (const file of files) {
			  		console.log(`${file.name} (${file.id})`);

			  }

The folder id of the root folder is "root". The file.list method has an option parameter called q which is used for searching.

 service.files.list({auth: auth,
    resource: { parents: [ folderId ] },
    q: "'root' in parents",
    fields: '*',
    spaces: 'drive',
    pageToken: pageToken,
  }

This code is kind of a guess as i dont have the power to test node on this machine.
