View only no download for Audio File by api

I am working of Dropbox .NET API to access the files and create shareable links.

I want to share some audio clip to other people, and I want that other people can just able to listen to the file, they must be not able to download those file.

In Dropbox .NET API I am creating a sharable link but I am not getting an option to restrict to just listen not download (I am getting this option on UI website when I click on the sharing link).

So my question is How it can be possible that other people just listen to the file other people should not able to download the file by dropbox .NET API?

Please share some code to do it!! currently, I am creating the link by the following code

DropboxClientConfig config = new DropboxClientConfig();
config.UserAgent = "Name of App";
DropboxClient dpc = new DropboxClient("***********", config);
RequestedVisibility visibility = RequestedVisibility.TeamOnly.Instance;
SharedLinkSettings sharedLinkSettings = new SharedLinkSettings(visibility,null,null );
CreateSharedLinkWithSettingsArg createSharedLinkWithSettingsArg = new CreateSharedLinkWithSettingsArg("path to file", sharedLinkSettings);

Thanks
