Common User Subsystem Login

Hello everyone, I have a question. I’m using the “CommonUserSubsystem” plugin, but I’m having trouble logging in. What I want to do is to ask us to log in when we first download the game, then automatically log in when we close and open it. How can I do this? I have one more question. In EOS Subsystem, I need to add accounts to devportal to be able to enter the game. How will we get rid of this process and how will players be able to enter the game directly?
