Please select the Storage menu on the left side. Here we can upload files JS, CSS, HTML, image, video, rar, and more. In order for the dashboard looks neat, I suggest to create the appropriate folder files that will be uploaded.
Please click the folder you have created to start uploading files, then please upload its files. Once the file is successfully uploaded please click on the file to get the URL and going out of the box on the right. Please click on the File Location → Download URL to copy the URL.
Done, easy is not it? I hope this helps
