I want to wait until all the files are downloaded before I show the start button but the button becomes active even before files are fully downloaded

let getFiles = async (paths) => {

let downloader = (args) => {

    return new Promise((resolve, reject) => {

        downloadManager = new Downloader();

        let promises = [];

        const documents = fs.knownFolders.documents();

        args.forEach((data, index) => {

            let file = exports.getFileName(data.pageUrl.downloadURL);
            let url = data.pageUrl.downloadURL;

            //check if this file was downloaded already
            const path = fs.path.join(documents.path,file);
            const exists = fs.File.exists(path);

            if (exists === false) { 

                let promise = downloadManager.createDownload({
                        path: fs.knownFolders.documents().path,
                        fileName: file,
                        url:url
                    });

                promises.push(promise);

            }

        });

        resolve(promises);
    })

}

let finishDownload = async (ids) => {
    page.bindingContext.downloadedFiles._array.splice(0);
    ids.forEach((data,index) => {
        downloadManager
        .start(data, (progressData) => {
            // console.log(data+" id: download value,",progressData.value);
            // console.log(data+" id: download speed,",progressData.speed);
        })
        .then(completed => {
            console.log(`downloaded File path: ${completed.path}`);

        }).catch(error => {
            console.log("downloadManager error: ",error.message);
        });
    })

   //this is always returned, even before files are downloaded.
    return "done";
}

let y = await downloader(paths);

let x = await finishDownload(y);

if (x === "done") {

    console.log("are we now finished!!!!!!!!");

    hideLoading();

    console.dir("all files are now downloaded and about to be saved!!!");

    let file = exports.getFileName(page.navigationContext.pages[0].pageUrl.downloadURL);

    //check if this file was downloaded already
    let documents = fs.knownFolders.documents();

    const path = fs.path.join(documents.path,file);
    const exists = fs.File.exists(path);

    if (exists) {
         modalContentButton.class = "modal-content-button-active";
    }
}

}

Can anyone assist with this? I think the issue is the finishDownload because it always returns before the files are downloaded and I cannot use an await before the downloadManager. If there is better way to do this please let me know.
