           if (canDisplayMessage(packet, "essentials.silentquit"))  { 
        
               String message = Utils.getPlayerLeaveMessage(packet.getParams().get("PLAYER_NAME")); 
        
               getServer().broadcastMessage(message); 
        
           }

Possible solution:

Use a channel only for the admin
Add a flag with ParamsKey and only those with the permission will receive the message
Find a way to check permission on offline player or move the check elsewhere

	if (canDisplayMessage(packet, "essentials.silentquit")) {
	String message = Utils.getPlayerLeaveMessage(packet.getParams().get("PLAYER_NAME"));
	getServer().broadcastMessage(message);
	}
