It looks like you are still initiating the pairing/connection from Vero.
I think this means put Vero in discoverable mode and do the pairing from Harmony to Vero.
I don’t have a Harmony remote so can’t really help with how it’s done. You can still leave bluetoothctl running to see messages but don’t issue any commands to it after the discoverable on command and discoverable off when (if) you establish a connection.
I think you may have to still issue a trust command in bluetoothctl so that Vero trusts Harmony in addition to Harmony trusting Vero.
@chillbo tells me his ‘just works’ with no faff but he may have a different Harmony model.
