Downloading Courses - Size of file

Does anyone use Rise, export the course to a SCORM file, and use that in an LMS which allows the users to download the course for offline use? We are trying to do this with our courses through our LMS but we embed videos from Vimeo so the videos don’t actually download for the user. Uploading all these videos into the course makes the size very large to download onto users’ devices. Is there some kind of media library within Articulate that could allow the size to be smaller? Curious if any other users are experiencing this issue and if there is another potential solution to the file size issue?
