Can anyone send me lives?

Hello and welcome to this community

I made 2 pictures for you. It's easy. Groups of players come to your game and above is the symbol with the 2 people. The symbol for friends. You can leave them with requests and enter an email address of your friends yourself and then he will be with you in your group. So you can send life back and forth. I hope that makes sense for you!

This is only possible on the PC.
