What is different about an Augustinian that might define Pope Leo XIV's papacy?

Cardinal Robert Prevost was made Pope Leo XIV today. He is the first Augustinian to become Pope as Pope Francis was the first Jesuit. It would seem that someone who accepted the order even prior to ordination would be very formed in some ethos and I don't know a whole lot about Augustinians other than I doubt the order was founded by St. Augustine and that Martin Luther was one. So what are the qualities might a young Robert Prevost have found in the Augustinian order that drew him to it which he might carry into his papacy?
