Send event to other server

[AlienKnow]

Please tell me how you can make such a system:
Example: let's say player A is playing on server 1, player B is playing on server 2

1. Player A wanted to invite player B to join the group.
2. player A throws an invitation to player B. /invite <Player B>
3. player B shows the "accept" and "reject" types in the chat, he clicks on the corresponding message in the chat and the event is performed.
4. A message is sent to player A whether the player accepted the invitation or declined

Well, something like that

Hello,

I'm understand what you're try to do. But that is not simple and I think you're post in wrong place, you need to post it on "Waterfall" since Paper is standalone server, If you're working on Network

And this is a place to get started (to read and self learning) https://www.spigotmc.org/wiki/sending-a-custom-plugin-message-from-bungeecord/
Well that not easy for beginer...
