headers when the platform fetches the file. The
content-type field must be present and accurate
in the HTTP response from the URL.

thumbnail.If you don't provide a thumbnail URI,
the RBM platform displays a blank placeholder
thumbnail until the user's device downloads the
file. Depending on the user's setting, the file
may not download automatically and may require
the user to tap a download button.
