In my trailhead module "assess the quality of data" challenge, it tells me to download the "data quality analysis dashboards app", when proceeding to the link to do this, a message comes up saying that only admin has permission or that I am able to download it in a free trial. How do I download this and other applications into my trailhead profile?
