MessagingService help

So, I am looking into MessagingService | Documentation - Roblox Creator Hub
and I am wanting to send some data to another game, for example I am working on a spawn system where if they leave a certain place into another game inside the game, it will spawn them in a different spot. How could I implement this?

How could I implement this into a system that shows where a player should spawn? This should only happen for one player btw

I still don’t understand your question, can you be more specific?
