Nice bag! I really like it! Where did you find it? I also like that little adapter you showed at the end of the video that allowed you to adapt your USB flash drives or external hard drives to the iPad Pro. One thing I have noticed with iPadOS is when I plug an external hard drive into my current iPad using a USB-C to USB-A adapter is the files app will not recognize an external harddrive but it will recognize a flash drive. The only resolution I have found to this problem is storing all of my documents and photos in the cloud especially OneDrive since I have a Windows PC and I found along with an iPad. It would be nice to have the ability to use external hard drives with the iPad but Apple has not made that possible yet.
