How can I set up an indicator for a second player's location?

Hey everyone, thanks in advance if you can help me with this.

Okay, so how can I do this? I plan on making big levels with two players and I want the players to be able to know where they both are. I mean, like in games like PUBG when you do Squads, an indicator that is an arrow pointing in the direction of the other player based on coordinates. So say one player is north, then on the 2nd player’s screen they will see the arrow pointing north. Does that make sense?

If that doesn’t work, maybe someone can direct me towards making a multiplayer mini map.
