Start with UE5 and Lyra (package and EOS)

I’m starting with UE5 and Lyra. I use EOS. I have these questions:

1- If I use EOS (the basic configuration). So far it allows me to log in using my Epic Games account, my question is: once I package my game and it is available for Windows and Macbook, does EOS allow me to use multiplayer, play online with friends? What else?

2- How do I package my Lyra game for Windows and Macbook? Is there a tutorial? Since I am new I am lost and I don’t know what I need and what I should do.

3- If I want to upload my game to Epic Game, do I need to compile and then upload it? What else?
