Unable to register device Dragino LHT65

I want to register a Dragino LHT65 Teperature and Humidity sensor.
I followed the documentation:

OTAA devices

After creating a device, you can manage the application-key (and network-key for LoRaWAN 1.1 devices) under the Keys (OTAA) tab. Under the Activation you will see the current device activation (if activated).

However after I set the checkbox “Device supports OTAA”, the remainder of the page is empty. THere is no input for application-key under Keys (OTAA) tab, in fact there is no Keys (OTAA) tab

is you set the correct device profile to corresponding device ?

Yes. But I had to create an Application, this is what I forgot
