Backup Original INSV files from Insta360 App Android

Hello,

I've recently switched to a new phone and i have some old footage stuck in my old Samsung Note8 device. I downloaded these files from my One R camera to have more space for new footage on my vacay and they now only exist on the phone. I can't find them in any visible folder that's accessible when connecting to my PC, nor on any file explorer app on the phone. I can however view them in the Insta360 App.

Anyone have a tip on how I can get the files out?
