How to upload multiple files using JavaScript SDK?

Hi, I am using Javascript SDK to upload multiple files at once. I have a dropbox business account enabled and the folder where I am trying to upload the files is a shared folder.

I want to upload the files to

root > Clients > Somefolder

Clients and Somefolder are the folders created by me.

Here's my code:

const uploadClientData = async (req, res) => {
	try {
		const files = req.files
		const { dbxUser } = req;
		const args = {
			contents: files,
			path: '/Clients/Wise',
			mode: 'add',
			autorename: true,
			mute: false,
			strict_conflict: false
		}
		await dbxUser.filesUpload(args);

		res.status(200).json({message: "Uploaded"});
	} catch (error) {
		console.log(error)
		res.status(500).json({
			error: error
        });
	}
}

And here my dropbox Initialization

module.exports = async (req, res, next) => {
    try {

        let dbxTeam = new DropboxTeam({ fetch: fetch });
        let access_token;

        dbxTeam.setClientId("XXXXXXXXXX");
        dbxTeam.setClientSecret("XXXXXXXXXX");
        
        if(req.body.code){
            access_token = await dbxTeam.getAccessTokenFromCode('http://localhost:3000/authentication', req.body.code);
        } else {
            let team_member_id = req.userData.team_member_id
            access_token = await helpers.getAdminDetails({team_member_id}, "access_token")
            access_token = access_token[0].access_token;
        }
        
        dbxTeam.setAccessToken(access_token);
        let { admin_profile } = await dbxTeam.teamTokenGetAuthenticatedAdmin()

        let dbxUser = new Dropbox({
            accessToken: access_token, 
            selectUser: admin_profile.team_member_id, 
            pathRoot: JSON.stringify({".tag": "root", "root": "5619027360"}) 
        })
        
        req.dbxTeam = dbxTeam,
        req.dbxUser = dbxUser
        next();
    } catch (error) {
        return res.status(500).json({
            message: 'Dropbox Init failed',
            error: error
        });
    }
};
