Connecting Herelink over usb for 'adb devices' for QGC update

I’m starting work on bringing the QGC version of Herelink up to date with latest QGC. I can’t get ‘adb devices’ to see it when I connect it over usb. I have turned on developer mode. I can see other android tablets I have connected but Herelink doesn’t show up. Is there something else I need to do?

Someone else found this which worked for them: My Android device does not appear in the list of adb devices - Stack Overflow

If so, would be good to update docs
