TestFlight: No "External Groups" option on app

Is there any way to enable the External Groups option in Test Flight? For some reason, on the last app added to connect, the option is not available -- not in the Connect iOS app or web interface. It's an iot app and controls a device. Could it be that the reviewer couldn't allow external testing because they app doesn't do much other than search for zeroconf/bonjour devices on the local network? Not sure how to proceed here and can't figure it out.

This is solved. I forgot one must create the external group before submitting the build for review.
