I am using SPPull but it downloads all the files in the folder I want to download specific files in a list

async function downloadFromSharePoint(path, projFolder, url, FilesToDownload) {
var fileOpts = {
    spRootFolder: "path + projFolder,
    dlRootFolder: "./downloads",
};
var context = {
    siteUrl: url,
    creds: {
        clientId: config.SHAREPOINT_CLIENTID,
        clientSecret: config.SHAREPOINT_CLIENTSECRET
    }
};
SPPull.download(context, fileOpts)
    .then(() => {
        console.log("Files are downloaded");
    })
    .catch((err) => {
        console.log("Core error has happened", err);
    });
}

I tried to add shouldDownloadFile in fileOpts and give it the list but all the files in the folder downloaded Anyone can help?
