Downloads the files uploaded into a guide step — a PDF handout, an image, a video, an audio clip. These are the attachments that make up the step's content; they are not a file representation of the step itself.

You shouldn't ever need to build these URLs directly. List Guide Steps returns them for any file-type step, so the normal flow is to list a guide's steps, read the file URL from the step, then call it. These URLs are stable as long as the step is not changed. If it is deleted or modified in a way that affects the file, the URLs will no longer be valid.

Example: archiving all the attachments and reference documents from a compliance guide into your own document store, or letting a separate app display a guide's PDF handout.
