How does Lutris work?

Question

Wine

I was interested in the function of launching games with discrete video forcibly, so here are the questions. How to add the entire PlayOnLinux library to lutris? Is it also possible to conveniently install games in Lutris according to the algorithm: created or selected a prefix, added libraries from the list, selected an executable file for installation, selected a shortcut and run it? Or is it just a gimmick to catalog all the games?
