Sambapos mobile

Hello everyone
I have always had to deal with the sambapos V5 version now I would like to learn how to activate the license for the mobile version. I could not understand the procedure described on
I would like someone to help me in this direction

It’s linked to the licence account, you pay licence per symiltanious connected devices.
Beleive it’s an annual payment.
Licence needs to be within account holding the main v5 licence
