Questions about Seat Connect

Evening, I have a few questions, I have an Eu import and therefore not the right manual for everything. I have entered Seat Connect on the mobile phone, the code no. in the vehicle and can therefore retrieve some data. But I can not retrieve all functions, then comes a message that I should perform the Seat Ident procedure and thus to Seat. What is this? Somewhere I have read something with two keys. And there was something else with the green LED on the SOS button. , what’s with it? Can someone tell me something about it? Thanks already. 🙂
