Skript - Mirror Event Help

[MeHow]

Hello guys I just started to work with skript-mirror and I cant understand it well so I can't make this skript:

on script load:
    import "org.bukkit.event.player.AsyncPlayerChatEvent"
    import "org.bukkit.entity.Player"
    import "org.bukkit.ChatColor"

       
on "org.bukkit.event.player.AsyncPlayerChatEvent":  
    if {m_.partner.%event.getPlayer()%} is not set:          
        set {_replace} to ChatColor.translateAlternateColorCodes("&", "&4&l&f")
    else:
        set {_replace} to ChatColor.translateAlternateColorCodes("&", "&4&l❤&f")
    set {_fromat} to event.getFormat().replace("{marry}", {_replace})
    event.setFormat({_fromat})

What I am doing wrong? I am trying to use Skript variable and use it with java

You don't have to import the event class to use the event, and you are using the java call expression wrong. I don't really see why you are doing this though, vanilla skript has both on chat and chat format
