Social Matchmaking and Unity

Love the platform!

I’m a pretty big novice and have a question.

I’m trying to build a game in unity (using the Jolly Roger platform as a base), I’ve got most of it completed but need some help with the following:

  1. User selects friend from friend list (have got FB integration running);
  2. This selection sends a message to the friend and a push notification to friend - this message is stored in a “my messages/challenges” list and displayed on the main menu
  3. Friend engages with notification or selects a “play” button in the “my messages/challenges” list;
  4. Match made and lobby built.

I was wondering what part of the Nakama codebase needs to be used to implement this functionality?

In particular the friend selection matchmake component.

Thanks so much for the help, I really appreciate it!
