GUI 1 client to all clients

[John NA]

I need it when a person clicks a button on their gui, it replicates on all clients that have the gui

I don't know if there is another way to this, this is my thought on the topic:

call the server from that 1 client and then send it to specific people, which might be costly in terms of performance.

Please let me know if there is another way to this. Performance is a must in my opinion

It sends message to server
Server send info to all clients
Sync and process info on client
