Its the way I could share files from synology on internet like file share services ?

hi all, I am looking the way, how I could give users web access to files on my synology, by means of conencting to specified website and they would see all folders structure and according to user privilegies, they would be able to upload/download files. They will not install anything to their computer, just access to website with shared files. Is there any way how to do it by Synology please ?

thanks for answers
