JDS Labs Core application USB connection

I am having trouble getting my JDS Labs Element IV to connect to the JDS Labs Core management/firmware update application. They have a webUSB based web app with specific Linux instructions which didn't work for me here: https://core.jdslabs.com/faq The clicking connect on the webapp in Chrome brings up a device list which includes the Element IV but selecting it produces a cannot connect error. Following the instructions above I get an error from usermod that group 'uucp" does not exist. Additionally they have Linux native client versions of the Core app which are supposed to not need any messing with permissions but still the same problem. I installed the AppImage with Gear Lever and the app runs, but once again won't connect to the device over USB. https://core.jdslabs.com/download-native-app The device works just fine as an audio output, just will not connect to the the Core app either through webUSB or the native AppImage application. I'm running Bazzite Gnome Desktop edition latest version.
