Dell Mobile Connect (DMC) taking up a lot of space on iPhone

My DMC app is using a whopping 13GB of space on my phone (iOS 13.3.1, DMC v3.0.2). When opening the app, there's nowhere to tap: it only shows that it's connect to my computer. I wonder what is taking up so much space and how can I get rid of it without having to delete the app. I appreciate all the help.
