Join MAC version 1.0.0 device to RAK server

Hi, I have some MultiTech mDot left over. I want to join to RAK server so that I can use them again. Does anyone has done this? I can’t get it to work so far.

I have changed RAK server to device-profile to LoraWAN Mac version 1.0.0, but usually, I need to setup Network Id and Network Key for join mDot, how it configures to join the RAK server?
