USB-C iPhones work with all kinds of USB-C hubs, devices, keyboards, mice, Ethernet adapters, etc out of the box.
As far as I have seen, USB-C on iOS devices has no authentication restrictions for anything.
The device in the article already has an iOS app, so while there may be a needed app entitlement, I don't think there are any showstoppers for making an iOS app for this particular thermal camera.
