The Asset Library connection starts with Google Drive read-only access. A Space can select multiple non-overlapping root folders, so useful material can stay split across campaign shoots, events, product photography, evergreen brand assets, and archives instead of being copied into one new social-media folder.
Somea indexes the selected brand-owned photos and videos for discovery. That gives a social media manager another way into the same library when the starting point is not a filename or folder path, but a visual need such as a product in use, a busy venue, a summer event, or a particular mood.
