Let's say I'm playing in a public game with someone and we hit it off. I want to officially become his friend, so that we can intentionally group later on. How do I do this?
I know how to find the list of recent players. I know how to find the list of people currently on my team. But in neither place does there seem to be a context option to become friends with that person.
I feel like I'm missing something obvious, but how do you invite someone you've played Overwatch with to become friends?
